ELECTRIC STARTER (TRX450ER)
STARTER RELAY SWITCH
OPERATION INSPECTION
Shift the transmission into neutral.
Turn the ignition switch to ON and push the starter
switch.
The coil is normal if the starter relay switch clicks.
If you don't hear the switch click, and inspect the
relay switch circuits (page 23-13).
CIRCUIT INSPECTION
Release the connector boot from the clamp remove
it off of the connectors.
GROUND LINE
Disconnect the starter relay switch 2P natural con-
nector.
Check for continuity between the Yellow/green wire
harness side connector terminal and ground.
If there is continuity when the transmission is in
neutral or when the transmission is in gear and the
clutch lever is squeezed, the ground circuit is nor-
mal. (In neutral, there is a slight resistance due to
the diode)
POWER INPUT LINE
Turn the ignition switch to ON.
Measure the voltage between the Yellow/red wire
terminal (+) of the wire harness side connector and
ground (-).
If the battery voltage appears only when the starter
switch is pushed, the circuit is normal.
