8.0 Output Protection Fuse Replacement
The Truecharge has two built-in 15 amp, 32 volt rated, automotive blade-type output
protection fuses. Their function is to protect the unit against reverse battery polarity
caused by incorrect installation. Should one or both fuses be blown, replace as
follows.
1. Disconnect AC power to the Truecharge and disconnect the DC cables
at the battery(s).
2. Remove the wiring compartment cover by removing the 4 screws that
attach it to the Truecharge.
3. Locate the fuses just inside the upper left corner of the wiring
compartment.
4. Pull each fuse directly toward the Truecharge’s mounting surface to
remove them from their fuseholders. Never pull towards the lower end
of the unit, or wiggle the fuses back and forth to remove them.
5. Replace any blown fuse with an identical 15 amp, 32 volt rated,
automotive blade-type fuse. Never substitute with any other type or
rating, or damage to the Truecharge may result.
6. Find and correct the problem that caused the fuse(s) to blow. Generally
this will be reversed battery polarity.
7. Replace the wiring compartment cover and reconnect AC and DC
power.
