3.4 Starting Relay
3.4.1 Actuation Inspection
Take down the protecting plate of vehicle block.
When the ignition switch is set at “ON” position, press starting
motor and a “Click” sound can be heard.
Inspect Sound.
“Click” sound indicates normal.
No sound: • Check starting relay voltage.
• Check starting relay ground wire loop.
• Inspect starting relay actuation.
3.4.2 Starting relay voltage inspection
Lift and support the main stand. Measure the voltage between
negative pole (green/yellow) of starting relay connector and
vehicle ground wire.
Set ignition switch at “ON” position and catch the brake lever. Battery voltage shall meet the specified.
When there is no voltage at wire terminal of starting relay, inspect braking switch continuity and lead wire.
3.4.3 Starting relay ground loop inspection
Remove starting relay connector.
Inspect continuiy between black wire of connector terminal
and vehicle ground wire.
When the starting button is pressed, continuity between black
wire of connector and vehicle ground wire shall be fine.
If there is no continuity, inspect starting button continuity and
lead wire.
3.4.4 Acutation Inspection
Connect starting relay with battery and connect terminal of
starting motor with multimeter.
Connect fully charged battery between black wire and
green/yellow wire of relay. A “tap” sound of operation can be
heard on the relay and resistance displayed by multimeter is
zero.
