Charger Ammeters

Charger Ammeters

This section contains replacement ammeters for a variety of voltages and amperages. Be sure to match the charger output volts & amps to the ammeter you intend to order. See our ammeter selection at the bottom of this page.

The ammeter on a 36-volt charger should show at least 15+ amps when the charger is plugged into the golf car, even if the batteries have not been used for a short while. A 15+ amp reading shows that the charger is actually charging, not just humming (humming is NOT an indication that the charger actually works). If the batteries are full, the ammeter reading will quickly drop below 15 amps. As the batteries charge the ammeter read out will eventually drop to about 2 or 3 amps. This indicates a near full charge in the batteries. If the batteries are getting old & feeble, the finish amp rate may not fall below 10, or even 15 amps. Don't cook the poor batteries trying to get them down to 2 or 3 amps. A 12 hour charge should bring the batteries to about as low a reading as they can achieve. A high finish rate indicates the batteries have done about all they can. Time to replace them all.

An ammeter does not need to show any amp reading for the charger to be working properly...but it should. Occasionally an ammeter needle will stick or not deflect up scale when charging but the charger still puts out sufficient amps & volts to charge the batteries. If a 36-volt charger is putting out 40+ volts then it is working, regardless of the ammeter reading. If the meter is flakey, replace it!

If the ammeter starts to get brown beads of sweat inside the glass cover it indicates a wire connected to the ammeter (inside the case) is starting to burn off. Open the case and fix the wire. The brown colored sweat beads do not mean the ammeter is always bad...just soon to go bad. Catch it early enough and you can save the meter.

CAUTION!! Always disconnect the charger from the AC wall circuit and from the golf car before opening the charger case.
