10.4 BATTERY CHARGER TROUBLESHOOTING

Inspect the charger for damage or loose components from mishandling or transport. The unit
should not rattle or have any loose parts.
Make sure the charger is being used on the correct input voltage and the selector switch
matches the input voltage.
Make sure the batteries have been connected correctly and there is not an issue with the
polarity of the connections.
Disconnect the charger from the battery turn off the mains power and wait 1 minute before
reconnecting the power.
• Do each of the LEDs turn on one at a time then leave the red power light on?
• This is a self-check of the charger and confirms the charger is free of faults.
• Manually check the leads to the charger for any damage.
Switch the charger back off, connect the charger to the battery, switch back on, the lights should
now flash in sequence again. The yellow charging light should now illuminate.
Is there any voltage in the battery?
If yes, it needs to be > 18V to make the charger work. Make sure voltage is measured
across all three batteries in series
Has the battery unit been left on and thus discharged the battery?
If yes, turn off and wait a few hours, then try again to charge the unit.
If unsure, try the charger on another unit. If the charger works on another unit, then the fault is
with the main unit, and not the charger.
Do not measure the output voltage of the charger without connecting to a battery. With no
battery connected the battery charger output will be 0V (zero). This is not a fault.
Check the fuse adjacent to power lead socket – spare fuse provided.
