AC Charger Test
AC Chargers rarely fail. The only known problems have been with the in-line fuse with the 24V chargers. We now replace this fuse with a Blade fuse, and it has not been a problem. Since an AC charger is regulated, it should not over-charge a battery. However, to test the charger, it needs to be hooked up to a battery.
- Verify the charger is plugged in. (LED should be on)
-Charger should only be plugged into a circuit with a Ground Fault Interuptor (GFI). - Check wiring of AC charger
- Red to positive post on battery
- Black to negative post on battery
- With the AC charger on the battery, measure the voltage of the battery using a volt meter. Voltage should be over 13V.
- Unplug the charger, and see if the voltage of the battery drops.
- If the voltage drops, charger is OK. If battery goes dead, check battery.
- If it doesn’t, check AC power (is charger LED on?), check fuse, check for submersion.
- If charger still doesn’t work Replace AC charger.
NOTES:
It is extremely rare for an 12V AC charger to go dead, but not uncommon for a fuse of a 24V charger to go bad with high heat. Add ventilation holes to Powerpack box if needed. Do not remove fuse, since this can cause an electrical fire.
