General Information, Continued:
To properly service and maintain this vehicle, it is necessary to understand the electrical circuitry and the
functions of all the electrical components. On any PowerDrive System 48 vehicle, there are four separate cir-
cuits in operation: 1) the control circuit, 2) the speed control circuit, 3) the power circuit, and 4) the charge cir-
cuit. A reverse buzzer is also included on every vehicle (See Page 20-29). When working on the electrical
system, refer to the appropriate electrical wiring diagram (Figures 20-2 and 20-3, Pages 20-3 and 20-4) for
more detailed information.
THE ON-BOARD COMPUTER (OBC)
Each PowerDrive System 48 vehicle is equipped with an on-board computer (OBC). The primary function of
the on-board computer is to control the battery charger. By continuously monitoring battery state of charge,
as well as the amount of energy consumed as the vehicle is used, the OBC is able to direct the battery
charger to replace exactly the amount of energy needed to replenish the batteries. The OBC uses this data
also to indicate possible battery or charging problems by illuminating a warning light in the dash (For more
information on the Battery Warning Light, see Section 23, Page 23-28). OBC data can also be useful in
performing electrical system diagnostics. A digital readout of OBC data can be obtained using the Club Car
Communication Display Module (CDM)(Club Car Part No. 1018318-01)(See page 20-22).
The chart in Figure 20-4, Page 20-6 is a quick reference guide to troubleshooting vehicle symptoms that
might be OBC related.
