TESTING PROCEDURE: Make SURE the Motorcycle is in NEUTRAL!!! Even with the ignition OFF! Before pulling an old solenoid off a Motorcycle, you can test it. Applying 12 volts to the two wires inside the plastic connector, the solenoid is polarity sensitive. Applying 12 volts in the wrong polarity doesn't hurt the solenoid, it simply won't work. When the 12 volts are applied to the two small wires correctly: If the starter cranks, the solenoid, the battery and the starter are all good. If the solenoid makes an audible click sound but your starter doesn't crank, the solenoid is good.
Note: This is an Aftermarket Replacement Part BUT NOT Genuine. This may or may not be a direct fit for the Motorcycles listed below! However, given the cost of an OEM replacement we think it's well worth the time you may spend installing it. See pictures for additional measurements to ensure this is the right starter relay for you!
Battery voltage stays within a steady range while the mower deck is engaged. The engine restarts confidently after long cutting sessions, and the headlights no longer change brightness with rpm.
Charging output stays consistent during low-speed riding with the cooling fan running. The battery remains strong after repeated starts, and the connector area shows no signs of overheating.
The truck starts without excessive pumping and settles into a stable idle once the choke releases. Throttle response is smooth when pulling away, and fuel delivery remains consistent while carrying a load.
The flex section absorbs engine movement without transferring vibration into the cabin. Acceleration sounds smoother, and the exhaust connections remain dry and soot-free around each flange.
Exhaust flow feels unrestricted again, especially when the vehicle accelerates with passengers or cargo. The system stays quiet at highway speed, and the emissions monitors complete without a recurring catalyst fault.
