SERVICE INFORMATION
GENERAL
•
Some wires have different colored bands around them near the connector. These are connected to other wires which
cor·
respond with the band
color.
•
All plastic plugs have locking tabs that must be released before disconnecting, and must be aligned when reconnecting.
•
The
following color codes are used throughout this section and on the wiring
diagram.

•
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 teste
r
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 involv·
ed,
or when check ing for high resistance caused by corroded
connections.
