My apologies for less than adequate info. The unit has a charger to the left side of the drive wheel with the hydraulic pump/motor to the right. the battery is new and sits in the middle of the Jack separate from the motors internal wiring and module. The main cables come in from the batter connector and run along the top to the module however the 10 amp fuse and the key switch is actually in line through the charger itself.

Newer versions of the charger look like this but this unit is a bit older and has the brass casing with no heat sinks
