Starter Solenoid Relay
How a sportbike starter solenoid works is when the handle bar start push button is pressed in the ignition switch is giving off a small electrical current to the starter solenoid. The idle starter solenoid is triggered to close and thru a heavy gauge pair of wires giving a much greater electrical current by the motorcycles battery to go thru the starter motor then sets the motor in motion.
How to test your starter solenoid relay with a volt meter and jumper wires:
Make sure you have good 30amp fuse in the starter relay before you do anything.
Step 1 Hook black jumper wire from 12 volt negative post of battery to green/red wire of terminal.
Step 2 Now hook red jumper wire from 12 volt positive post of battery to yellow/red wire terminal. When you hook this wire up, You will hear a click. This clicking sound is the contacts in the starter relay.
SAFETY WARNING! Once starter relay is activated, only takes a minute and it will get extremely HOT. Remove red jumper wire as soon as test is completed.
Step 3 Use your continuity tester on the large terminals of the starter relay. B is battery and M is starter motor.
There should be continuity between the large terminals while the battery is connected, and no continuity when the battery is disconnected.
