SAFETY

• Carefully read all operating instructions before using the tester
• Wear eye protection when working around batteries.
• Be sure each test is completed before removing load clamps to prevent arcing and potential explosion from battery gasses. Never remove load clamps while testing. Keep sparks, flames, or cigarettes away from batteries.
• Keep hair, hands, and clothing as well as tester leads and cords away from moving blades and belts.
• Provide adequate ventilation to remove car exhaust.
• In extremely cold temperatures, check for frozen electrolytic fluid before applying load. Do not attempt to Load Test or charge a battery under 20 degrees. Allow the battery to warm to room temperature before testing or charging.
• Warning! Never attach the unit to a battery that is connected to any other tester or charging unit. Damage may result.

CAUSE OF BATTERY FAILURE

• Incorrect Application: Wrong size battery may have inadequate cold cranking rating for original vehicle specifications.
• Incorrect Installation: Loose battery hold-downs cause excessive vibration, which can result in damage to the plates.
• Improper Maintenance: Low electrolytic fluid and corrosion on battery connections can greatly reduce battery life and affect battery performance.
• Age of Battery: If the date code on the battery indicates it is fairly old, the failure may be due to natural causes.
• Overcharging: Overcharging caused by a high voltage regulator setting or incorrect battery charging can cause excessive gassing, heat and water loss.
• Undercharging: Undercharging caused by a faulty charging system or low voltage regulation can cause lead sulfate to gradually build up and crystallize on the plates greatly reducing the battery’s capacity and ability to be recharged.

Cardboard load holder for shipping
In the event your tester needs to be returned to Auto Meter Service,it must be properly packaged and protected to avoid damage during shipment. Failure to follow these steps will allow the carbon disks to rattle freely during shipment and cause breakage. Before packing the tester for return shipment, turn load knob fully clockwise until it stops, hold in position and slip a snugly fit cardboard holder over the load knob. This will then rest against the cables and prevent the load knob from turning back. The load knob holder must be 3-1/2” by 9-3/4” with a 2-3/16” hole cut out in the center and slightly off set (copy and use template at right). Please use a thick enough piece of cardboard, preferably corrugated, to prevent bending and slippage of the load knob.

SERVICE INFORMATION

Warranty claims to Solar must be transportation prepaid and accompanied by dated proof of purchase. This warranty applies only the original purchaser and is non-transferable.
Damage incurred during return shipment is not covered under this warranty. It is the responsibility of the shipper (customer returning tester) to package the tester properly to prevent damage during return shipment. Repair costs for such damages will be charged back to shipper (customer returning tester).
Before packing tester for return shipment, tighten load knob to prevent breakage of carbon discs during shipment due to rattling. Also protect the meters and add plenty of over-pack cushioning such as crumpled-up newspaper.

BATTERY INSPECTION

Valid automotive electrical system testing depends on all the components being in good operating condition. In addition, the battery MUST have sufficient charge for testing. Carefully perform the following before attempting any electrical diagnosis.

VISUAL CHECK

• Inspect Battery for terminal corrosion, loose or broken posts, cracks in the case, loose hold-downs, low electrolyte level, moisture, and dirt around the terminal.
• Important Note: A known defective battery must be replaced before proceeding with any test on the charging or starting system.
• Inspect Belts for cracks, glazed surface and fraying. Tighten loose belts. Inspect belt tensioner for proper alignment.
• Inspect Starting System. Check starter, solenoid, and alternator for loose connections, loose mounts and frayed or cracked wires.

PRELIMINARY NOTES

MOISTURE
If tester has not been used for a period of time, moisture may have condensed between carbon pile discs. This will cause the tester to steam a little during first or second load application. This is normal and is not a malfunction of the tester. (Do not confuse this with heat due to overloading the tester.)

BATTERY RATING
Most batteries are rated in Cold Crank Amps or Amp-Hours. This tester uses a stabilized variable load carbon pile that allows each battery to be tested at its proper rating. For batteries rated in Cold Crank Amps, a load equal to one half the rated CCA is applied using the Amps scale on the meter. For Amp-Hour rated batteries, a load three times the Amp-Hour rating is applied using the Amp scale.

BATTERY TEMPERATURE
The temperature of the electrolyte and plates inside a battery affects its output capability. As a result,it is necessary for the service technician to closely estimate the battery’s temperature when testing. This tester has temperature ranges clearly shown on Pass/Fail bands, so that accurate test results can be obtained easily.

TESTER HOOKUP
Take special care when connecting to side terminal batteries. If necessary, use a side post adapter to prevent thread damage. When testing dual post batteries always check the post to which the system is attached. If a load test is made from a post connection and the alternator is mounted to side terminals a battery load test can be completed, but a continuity problem may still be
in the side terminals when testing the alternator.

ALTERNATOR TESTS

Using the hookup above follow test procedures on page 12.

6 or 12 Volt System Tests Using Single Or Multiple Batteries Connected In Parallel

Use the scale appropriate for the system test. Follow the test procedures on page 12.

APPENDIX

MULTIPLE BATTERY SYSTEM TESTS
In heavy duty applications, 6 and 12 volt charging systems are created by combining 6 and 12 Volt batteries in various combinations.
For a valid test, batteries must be tested individually, and the charging system must be tested at its rated voltage (6 or 12 Volts).

CAUTION: Care must be taken when disconnecting battery cables to prevent shorting of loose cables to ground or positive. Arcing caused by shorting cables can ignite hydrogen gas found in batteries and cause an explosion.
The proper way to prevent arcing at battery is by disconnecting the ground cable at the chassis or engine block and preventing it from contacting any metal. Then the remaining cables can be disconnected safely at each battery.

WARNING: Be sure load is off before attaching or removing load clamps to prevent arcing and potential explosion from battery gases. Always shield eyes and keep sparks, flames or cigarettes away from batteries.

6 VOLT BATTERY LOAD TEST

NOTE:
Regardless of the configuration all Six Volt Batteries are checked and load tested individually using the 6 volt scale. Follow battery load test procedure on page 9.

CONTROLS AND FUNCTIONS

TIMER LIGHT:
Indicates timer is on.

15 SECOND TIMER BUTTON:
Push to start the 15 second timer.

LOAD KNOB:
Turns the fan on and controls the amount of load during the test.

FAN OVERRIDE ON LIGHT:
Indicates when the fans override switch is on.

FAN OVERRIDE SWITCH:
The fan normally goes on automatically when the load knob is turned on and when released the fan turns off automatically. In repeated tests it is suggested that the fan override switch be turned on. This keeps the fan on for better cooling.

BATTERY STATE OF CHARGE

The battery must have an adequate state of charge before a valid battery load test can be performed. The state of charge can be measured with a hydrometer (see Appendix A page 16), or checked by the “state of charge” scale on the voltmeter for sealed batteries.

Read the 12 volt range (12 Volt Batteries) or the 6 volt range (6 Volt batteries) on the voltmeter, If the meter reads on the left side, in the red zone of the “state of charge” scale, the battery must be charged. See Appendix B page 17 for charging. Charge at a current rate as shown in Appendix B. This rate is determined by battery category type, which relates to reserve capacity in minutes.
After charging the battery, the surface charge must be removed before testing can begin. Surface charge will cause a higher voltage reading, which is incorrect. To remove the surface charge, turn the load knob to apply 1/2 the cold crank rating load or 3 times the amp-hour rating to the battery for 5 seconds. Wait several minutes after removing load and check “state of charge”. If the meter reads in the charge zone, replace battery (see example above). If the voltmeter reads in the “test” band (see example below), the battery is ready for the “battery load test”.

BATTERY VOLTAGE CHART

HYDROMETER METHOD

Check the electrolyte specific gravity with a hydrometer. If the specific gravity measures between 1.100 and 1.220, the battery must be recharged. If the specific gravity is between 1.225 and 1.265, the battery is ok to test. If the hydrometer has a temperature correction chart, be sure to adjust the reading for the battery’s temperature.
Variance of specific gravity between cells is not significant on discharged batteries (batteries with specific gravities below 1.225). However, if there is a variance of 50 points (0.050) in a battery whose specific gravity is 1225 or more, that battery is defective.

NOTE: A defective battery must be replaced before proceeding with any electrical system tests.

BATTERY LOAD TEST

1. Turn load knob to apply a load equal to 1/2 the Cold Crank rating or 3 times the Amp-Hour rating for 15 seconds.
2. Hold proper load for 15 seconds, observe the voltage reading, and then immediately decrease the load until the fan stops and the ammeter reads zero.
3. If the Voltmeter reads in the green zone for the approximate battery temperature, the battery passed the load test (see example above). If the Voltmeter reads in the red zone, replace the battery (see example below). Use the battery Voltage Chart in Appendix B page 17 to compare test results.

NOTE: For Multiple Battery System Tests see Appendix C

WARNING: Be sure load is off before attaching or removing load clamps to prevent arcing and potential explosion from battery gases. Always shield eyes and keep sparks, flames or cigarettes away from batteries.

STARTER DRAW TEST

For proper starter functioning, it is important that all related connections are clean and tight, and that the cable and its insulation are in good condition.

On all starter circuit tests, disable ignition circuit by one of the following methods:

• STD. IGNITION- (Points & Cond.): Ground coil output.
• ELEC. IGNITION- (Module): Disconnect 12V power supply.
• DIESEL: Disconnect 12V power supply to fuel shut-off solenoid.

The battery voltage will drop when it is loaded by the starter or with the tester. The Amp reading (when the tester yields the same loaded voltage as the starter) is the starter draw.

1. DETERMINING THE LOADED VOLTAGE USING THE STARTER:
   Crank engine and observe the voltmeter reading. Do not crank engine over 7 seconds at one time to eliminate possible damage to starter windings.

2. CHECKING THE AMPS USING THE TESTER TO DELIVER THE SAME LOADED VOLTAGE: The tester is used as a load to simulate the starter load. This is done by applying a load until the voltage drops to the same voltage observed while cranking the engine. Thus, the tester load amps indicated in the black 0-800 scale are the same as the starter amp load. Read amps indicated on the scale while load is applied (see example on page 11). This is the starter-draw current. Compare amp draw to manufacturer specifications.

3. To check the ground circuit, connect the RED clamp directly to the starter casing (this may require chipping paint to make a good connection), and the BLACK clamp to the battery negative terminal as shown in example below.

4. While cranking the engine, observe the voltmeter. The voltage drop should not exceed 0.3 volts. The total of the two tests should not exceed 0.8 volts. If positive says .5 and negative says .3 then the total is .8 Volts.

Example:

0.5 volts on the positive circuit
+ 0.3 volts on the ground circuit
.8 total system voltage drop

STARTER CIRCUIT TEST

Disable ignition as indicated in the Starter-Draw Test on page 10.

1. Connect the tester as shown below. A with the RED clamp to battery positive and the BLACK clamp to the terminal on the starter, which is connected to the solenoid directly or by cable.
2. Observe the voltage reading while cranking the engine.
3. On most vehicles, the reading should not exceed 0.5 volts (see example below).
4. If the voltage drop exceeds 0.5 volts, check the voltage drop through each cable, across each connection including the solenoid.
5. Repair and/or replace as necessary.

Example:

1. With ignition disabled crank vehicle and observe lowest volt reading. For this example, we’ll say it reads 11 volts.
2. Apply a load with the Load knob until voltmeter reads 11 volts (see example page 10). Quickly read the ammeter. In this case it reads 240 amps. Remove the load (knob turned fully counterclockwise).
3. We now know the starter draw is 240 amps and that it is generally within specifications for a V8 gasoline engine (see Maximum Amps chart on page 11).

Maximum Amps
If manufacturer’s specifications are not available, the chart below can be used as a general guideline for light duty engines and starters. Amounts are in Amps.

ALTERNATOR TEST

To charge a battery, the alternator must produce a voltage higher than the battery voltage to cause current to flow into it. Therefore, the voltage must rise to the “OK” test zone of the ALT. & REG. TEST band.
Before testing, run the vehicle’s engine at fast idle with all the accessories off for at least 5 minutes to recharge the battery and to stabilize the temperature of the alternator. (Remember, the following tests are valid only if the battery has passed the Battery Load Test (See page 9). For the following tests, continue running the engine at fast idle).
The battery is recharged when the voltmeter reading has stabilized at its highest reading. Observe the voltmeter reading in the “ALT. & REG. TEST” band:

REGULATION:

1. If in HI zone (See Figure A): Apply a normal accessory load, such as lights, heater and wipers.

2. If the reading drops more than 0.5 volts, there may be a wiring and/or connector problem between the alternator output and battery positive (+). If the alternator is producing adequate charge, and the pointer stays in the OK band, the charging system is OK, and the test is complete (see Fig. B).

3. If the meter is in the low band replace the alternator (see Fig. C)
   OUTPUT:

4. Apply a Load upon the battery until the Volts drop to 12.6 to 12.8. At that moment, read Amps and add the key draw amps (10-20 Amps). The Load Amps + Key Draw Amps = Total alternator output.

Troubleshooting: Alternator (Hypothetical Situation)

Problem: Customer returns continually because his battery keeps running down, but all battery and alternator tests pass.

Solutions:

• If alternator reads in the low end of the OK range, it is working fine. For people driving short distances, however, the battery may not charge fast enough, causing the battery to run down slowly. A higher amperage alternator may be necessary to insure faster charging.

• Some shorting or grounding may occur and slowly drain battery. Use a low range ammeter and check to see
  that no current flows from the battery with engine and
  all accessories turned off (including clocks). If current is flowing, locate cause and repair. Look for such things as trunk, hood, ashtray and glove compartment lights, bad switches, etc.

• Ammeters installed after vehicle manufacture may not have sufficient wire gauge to carry current without causing a voltage drop. This can reduce battery-charging rate, Measure the voltage drop from battery positive to alternator output terminal. If the drop is greater than 0.5 volts, and all connections are clean and tight replace all wire between the two points with wire that is one gauge heavier.

• Aftermarket accessories may add enough load to the charging system to exceed alternator capacity (i.e., stereos, telephones, defoggers, etc.). Replace alternator with one of higher capacity.

Dual Battery System

• When load testing check each battery separately with cables disconnected, so a problem with one battery is not masked by another battery.
• Charging system should be checked with both batteries connected.
• Accessories may be connected to one or both batteries. Be alert to their wiring differences in testing for problems.
