THE CHARGE CIRCUIT
The vehicle charge circuit consists of the following components:
•
charger receptacle
•
receptacle fuse link
•
onboard computer
•
batteries
The negative terminal of the receptacle is connected to the onboard computer. The 10-gauge black wire from
the onboard computer connects to the B– terminal on the speed controller, and the 4-gauge black wire (also
on the controller B– terminal) goes through the onboard computer and connects to the negative (–) post of
battery no. 8. The positive terminal of the charger receptacle is connected to the positive (+) post of battery
no. 1 (depending on the specific vehicle model, this connection to positive (+) post of battery no. 1 is some-
times made through another electrical component such as a solenoid, or main power fuse). The gray wire
(sense lead) from the charger receptacle is connected to the sense lead fuse, which is connected to the gray
wire from the onboard computer.
If the charger works with one vehicle, but does not work with another vehicle, then most likely the problem is
in the vehicle charge circuit. Check the connections between the 18-gauge gray wire from the charger recep-
tacle, the sense lead fuse, and the 18-gauge gray wire from the onboard computer. Also check connections
of the fuse link located on the charger receptacle
