How do you check to see if selonid is working on a Yamaha 600 grizzly?

To check if the solenoid is working on a Yamaha 600 Grizzly, first, ensure the battery is fully charged and connections are secure. Then, use a multimeter to test the solenoid by measuring the voltage at the solenoid terminals while attempting to start the engine. If you hear a click but the engine doesn't turn over, the solenoid may be faulty. Additionally, you can bypass the solenoid temporarily by connecting the two main terminals with a jumper wire to see if the starter engages.
