PRECEDENT – 6 X 8-VOLT
The vehicle charge circuit consists of the following components:
•
charger receptacle
•
onboard computer
•
batteries
The negative terminal of the receptacle is connected to the onboard computer
(Figure 3-6, Page 3-7)
. The
10-gauge black wire from the onboard computer connects to the B– terminal on the speed controller, and the
6-gauge black wire (also on the controller B– terminal) goes through the onboard computer and connects to
the negative (–) post of battery no. 6. The positive terminal of the charger receptacle is connected to the pos-
itive (+) post of battery no. 1. The gray wire from the onboard computer is connected to the charger recepta-
cle.
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 wire continuity and connections between the charger receptacle, onboard
computer and batteries
