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.
• All plastic connectors have locking tabs that must be released before disconnecting, and must be aligned when
reconnecting.
• The following color codes used are indicated throughout this section and on the wiring diagram.
Bu = Blue
Bl = Black
Br = Brown
G = Green
Gr = Grey
Lb = Light Blue
Lg = Light Green
О = Orange
P = Pink
R = Red
W = White
Y = Yellow
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.
