Starter Relay Switch B Inspection - Honda GL1800 Service Manual

STARTER RELAY SWITCH B
• Check that starter relay switch A operates prop-
erly before inspecting starter relay switch B.
Make sure that the engine stop switch is turned to
" " and the reverse shift switch is pushed to
"OFF."
Remove the left saddlebag (page 2-15).
INSPECTION
Shift the transmission into neutral.
Turn the ignition switch to "ON" and push the
starter/ reverse switch.
The coil is normal if starter relay switch B clicks.
If you don't hear the switch "click," turn the ignition
switch to "OFF," disconnect the 2P white connector
of starter relay switch B and check the following:
RELAY COIL GROUND LINE
Check for continuity between the Green/red wire
(ground line) terminal of the wire harness side con-
nector and ground.
If there is continuity, the ground line is normal.
(There is a slight resistance due to the diode.)
RELAY COIL INPUT VOLTAGE 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 battery voltage is present only when the starter/
reverse switch is pushed in, the input voltage line is
normal.
OPERATION CHECK
Disconnect the starter relay switch and starter/
reverse motor cables from starter relay switch B.
Connect a fully charged 12-V battery to the connec-
tor terminals of starter relay switch B.
CONNECTION:
Battery (+) terminal – Yellow/red wire terminal
Battery (–) terminal – Green/red wire terminal
There should be continuity between the cable termi-
nals while the battery is connected, and no continu-
ity when the battery is disconnected.
