FAQ

1. How loud should the charger be?
   The noticeable sound of rushing air from the fan is a normal part of the cooling process on your FORM rapid charger.

2. How warm do FORM chargers get?
   The FORM battery chargers can reach 140o F. They may get warm in an enclosed area. The maximum recommended air temperature for charging batteries is 105o F. When the charger is hot, the output current will drop to protect the charger and the battery.

3. Will I damage my batteries if I leave the charger plugged in over long periods of non-use (like storage)?
   No. FORM’s chargers will periodically check to ensure the batteries are topped off. This will allow you to keep your battery charger plugged in for long periods of time without “boiling the battery dry.” NOTE: It is important to check the electrolyte level approximately every 30 days. Batteries should be filled after charging, and the electrolyte level should be even in all cells and below the fill well in each cell. If the battery plates are exposed before charging, add just enough water to cover the plates. If the battery is overfilled before charging, it may overflow during charging.

4. Why does the LED on my FORM charger stay illuminated for a period of time after being unplugged from AC power?
   This is normal and does not affect your batteries. It is simply a function of the precision charging, ensuring the charger is disconnected prior to terminating the charge cycle.

5. What is the warranty?
   The manufacturer’s warranty is 18 months. You may return the charger up to 30 days after the date of delivery.

6. Can this be used at an input voltage of 240Vac?
   No, this charger is designed for 120Vac

7. The Batteries sound like they are boiling
   The batteries are not boiling. The sound you hear is the release of hydrogen gas bubbles during the bulk recharge phase. The release of hydrogen gas bubbles stirs up the sediment in the bottom of the batteries and helps to maintain a healthy environment

8. The battery meter on my cart reads less than full after a charge cycle.
   Aftermarket battery meters need to be calibrated correctly to read an accurate charge. Please consult the battery meter documentation on how to calibrate the meter.

9. The CHARGE STATUS Light is Green / Red flashing, but nothing happens when you insert the output plug into your golf cart.

   • Check if the output plug is fully inserted into the golf cart.
   • Check if there are any loose or corroded connections on your battery terminals.

10. Are your batteries completely dead?
    The charger must detect a minimum voltage of 18V from your batteries to begin charging; this is a safety feature to protect the health of your batteries. You may use a multimeter to check the voltage of your batteries. This can be solved by using an Automotive Trickle Charger and charging each battery individually to bring them up to the minimum voltage. Refer to the troubleshooting section “3.6 Reconditioning Golf Cart Batteries (Trickle Charging)”. Your cart has been charging for multiple hours, but the HARGE STATUS has not turned green. A 36V or 48V cart that has depleted the batteries to 50% will typically take between 7-10 hours to fully charge. This charging time can vary widely depending on the type, age, and health of your batteries.

TROUBLESHOOTING

Step 1 – VERIFY YOUR AC OUTLET IS WORKING

• Symptoms:
  No LED lights are lit up when the charger is plugged into the wall

• Helpful Hints:
  Garage and external home outlet issues are a common culprits of a golf cart chargers not turning on

Outlet Reset
Check if the AC wall outlet is a GFCI outlet that has been tripped. Press the red reset button to correct the potential issue. Plug your charger back into the AC outlet and see if the problem has been corrected.

Checking Breaker Panel

• Locate the breaker panel in your home and check for any fuses that have been tripped and show an orange indication.
• If a breaker is showing orange, turn off the break and turn it back on to reset.
• Plug your charger back into the AC outlet and see if the problem has been corrected.

Known Working Outlet

• Plug your charger into a known working outlet inside your home to verify if the charger lights will illuminate.

Step 2 – CHECKING CONNECTIONS & COMMON ISSUES

Symptoms:

• The fan on the charger will not turn on when plugged into the golf cart
• The charger does not enter charging mode when plugged into the charging port of the golf cart

Helpful Hints:

• Battery cables can come loose over extended use.
• It is recommended that you replace your battery cables at the same time you replace your batteries. Battery cables may frey or break internally with stress over time and create a weak or broken connection

Battery Cables

• Check that all the battery cables are tight against the battery terminals by grabbing the wire and trying to move it back and forth. If you can move the cable the connection is too loose

Corrosion
Check for any signs of corrosion on the battery terminals. If corrosion occurs, use a mixture of 1 tablespoon of baking soda mixed with 1 cup of water and a wire brush to clean the terminals. (We recommend performing this step outside to avoid a mess inside of your garage)

Tow/Run Switch
Lift your golf cart’s seat and locate the Tow/Run toggle switch. Ensure your cart is in RUN mode.

Parking Brake
Check to ensure the parking brake has been fully engaged on your golf cart.

Key Ignition
Ensure that the key on the golf cart is in the off position

STEP 3 – TESTING YOUR BATTERIES Symptoms:

• The fan on the charger will not turn on when plugged into the golf cart
• The charger does not enter charging mode when plugged into the charging port of the golf cart
• If you are receiving the error message low voltage error code on your FORM Charger

Helpful Hints:

• Batteries drain over time whether they are in use or not.
• If it has been longer than 30 days since you last charged your cart, your batteries are likely too low to accept a charge from a golf cart charger and an automotive trickle charger will be required to recondition your batteries.
• A 36 Volt golf cart has a safety requirement of a minimum of 18 volts for the charger to start working.
• A 48 Volt golf cart has a safety requirement of a minimum of 24 volts for the charger to start working.
• If you plan to leave your cart for more than 7 days, we recommend putting your cart in TOW mode to reduce the drain on the battery.

Proper Battery Water Level
Check the water level on each cell of your batteries to ensure they are filled with distilled water to a maxim of ¼’ above the plates inside of the battery.

Checking for Power
Step on the throttle pedal; does it go? If not, your batteries are likely below the minimum voltage for a golf cart charger to begin safely charging.

Testing the Pack Voltage of Golf Cart Batteries

• To test your battery’s voltage, you will need a multimeter.
• Set the multimeter to DC Voltage (Symbol for DC Voltage below). Make sure it is set for at least 2 place values
• Place the red multimeter probe on the positive terminal of battery 1 of your golf cart. Battery 1 can be identified as the battery that has the primary positive lead coming from the cart.
• Place the black multimeter probe on the negative terminal of battery 6 for carts with 6 batteries or battery 8 for carts that have 8 batteries. This battery can be identified by the battery with the primary negative lead coming from the cart
• You should be reading a minimum of 18 volts for 36-volt golf carts or a minimum of 24 volts for 48-volt golf carts. If you do not have the minimum voltage please proceed to Step 3.6 Reconditioning Golf Cart Batteries

Testing Individual Battery Voltage

• Utilize the same multimeter settings from Step 3.3
• Test each individual battery and record the results
• If any of the batteries have a voltage difference from each other greater than 1 volt, it will need to be checked by a golf cart mechanic for a dead cell.

Testing the Golf Cart Receptacle for Voltage

• With the multimeter on the same setting now test the voltage at the receptacle, it should be the same voltage that the main battery pack reads.
• If the voltage is not reading at the receptacle, or the voltage is different, there may be a wire connected incorrectly, or loose.

Reconditioning Golf Cart Batteries (Trickle Charging)

• Disconnect the golf cart charger from your cart
• Start by connecting the positive and negative leads of an automotive trickle charger to battery 1 in your golf cart. (The wires between each battery do not need to be disconnected)
• Turn on the trickle charger and let it charge for approximately 30 minutes. Repeat this step for each of your batteries
• After you have charged each battery individually repeat “3.3 Testing the Pack Voltage of Golf Cart Batteries”
• If your pack voltage is testing above 18 volts for 36-volt carts or 24 volts for 48-volt carts you may resume charging with your golf cart charger. If your pack voltage remains under the minimum, please repeat charging each battery individually with the trickle charger
