Foxwell BT715 Battery Analyzer

Description Overview

BT705 BATTERY ANALYZER
The latest BT-705 Battery Analyzer from Foxwell is dedicatedly developed to test 12V regular flooded, AGM flat plate, AGM spiral and gel batteries and 12V & 24V starting and charging system. It provides a quick, easy and affordable solution for technicians to check battery health and detect faults of starting and charging system. Main functions include battery test, cranking test, and charging system test.

Operation

Connecting The Tester

1. Clean the battery posts or side terminals.
2. Connect the red clamp to the positive(+) terminal and the black clamp to the negative(-) terminal.
3. Rock the clamps back and forth to make sure the clamps are firmly connected. In case the connection is poor, a “CHECK CONNECTION” message displays.
4. When the tester is correctly connected, it boots up automatically and show the voltage of the battery.

Battery Test

1. Press the MENU button to go to the Main Menu.
2. Enter BATTERY TEST, select the Voltage, TEST TYPE, BAT Location, POST TYPE, BATTERY TYPE, BATTERY STANDARD and the corrected Battery Rating.
3. View test results on the screen. Depending on battery status, one of the following test results may display.

Cranking Test

Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the rpm levels needed for the test. After an in-car battery test, the display alternates between the battery test results and the message PRESS FOR CRANKING TEST displays.

1. Press the ENTER button for the cranking test.
2. Start the engine when prompted.
3. The tester displays the decision on the starter system, cranking voltage, and cranking time in seconds. For instance, as below display, the starter system is REPLACE BATTERY, the cranking voltage is 10.76 V, and the cranking time in seconds is 0.86 S.
4. Press the ENTER button to proceed with the charging system test, and the BACK button to return to the main menu.

Test Results/Interpretation

1. CRANKING NORMAL
   The starter voltage is normal and the battery is fully charged.

2. LOW VOLTAGE
   The starter voltage is low and the battery is fully charged.

3. CHARGE BATTERY
   The starter voltage is low and the battery is discharged. Fully charge the battery and repeat the starter system test.

4. REPLACE BATTERY
   The battery must be replaced before the starting system can be tested.

5. NO START
   No vehicle starting detected.

6. CRANKING SKIPPED
   A start was not detected.

Charging System test

Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the proper tension, will prevent the engine from achieving the rpm levels needed for the test. Once you have completed an in- vehicle test, the display alternates between the battery test results and the message press ENTER for the charging test. Press ENTER to proceed with the charging test.

1. Follow the on-screen prompts to Rev the engine.
2. Turn on high beams headlights and the blower fan.
3. Rev engine with loads on.
4. Idle the engine and turn off loads.
5. The Charging System decision is displayed at the end of the procedure.

Test Results/Interpretation

1. NO PROBLEMS
   The system is showing normal output from the alternator.

2. NO OUTPUT

   • No alternator output was detected.
   • Check all connections to and from the alternator, especially the connection to the battery. If the connection is loose or heavily corroded, clean or replace the cable and retest.
   • If the belts and connections are in good working condition, replace the alternator. (Older vehicles use external voltage regulators, which may require only the replacement of the voltage regulator.)

3. LOW OUTPUT

   • The alternator not providing sufficient to power the system’s electrical loads and charge the battery.
   • Check the belts to ensure the alternator is rotating with the engine running. Replace broken or slipping belts and retest.
   • Check the connections from the alternator to the battery. If the connection is loose or heavily corroded, clean or reparable the cable and retest.

4. HIGH OUTPUT
   Alternator voltage output exceeds the normal limits. Make sure there are no loose connections and the ground connection is normal. If there are no connection problems, replace the regulator. Most alternators have a built-in regulator that requires replacing the alternator. In older vehicles that use external voltage regulators, you may need to replace only the voltage regulator.

5. EXCESSIVE RIPPLE

   • Excessive AC ripple detected.
   • One or more diodes in the alternator are not functioning or there is stator damage.
