SERVICE INFORMATION
GENERAL
• Some wires have different colored bands around them near the connector. These are connected to other wires which have
the same color band.

Br = Brown
G = Green
Gr = Grey

To isolate an electrical failure, check the continuity of the electrical path through the part, A continuity check can usually
be made without removing the part from the motorcycle. Simply disconnect the wires and connect a continuity tester or
volt-ohmmeter to the terminals or connections.
A continuity tester is useful when checking to find out whether or not there is an electrical connection between the two
points. An ohmmeter is needed to measure the resistance of a circuit, such as when there is a specific coil resistance in-
volved, or when checking for high resistance caused by corroded connections.
