Electric Drive Components
The following section will help to identify the components, and conduct tests to identify problems within the
electrical system.
General System Description
The XTR electric PowerBoards use two 12 Volt batteries in tandem to supply current to a 450 Watt continuous
electric motor, (300 Watts on the earliest version).

Power is managed by a CPU controller board mounted to the front of the battery compartment, (Fig. 21).
High tension leads connect the system to a circuit breaker to protect the controller board from overload. The
XTR PowerBoards have used several different versions of circuit boards to accommodate slight differences in
the features and placement of components. Before ordering circuit boards as spare parts, be sure to identify
the number on the actual circuit board as it will be necessary to ensure ordering the correct part, (Fig. 22).
Newer models utilize a controller board mounted inside a sealed case. This helps prevent contamination from
dirt and moisture. (Fig. 22A)
