Specs At A Glance

Good To Know

Q: What are the signs that the starter relay has failed? A: A single loud click with no cranking, or complete silence when the start button is pressed, are the most common symptoms. Checking for voltage at the starter cable while cranking confirms the relay is at fault.

Q: Will this relay work on both the Yamaha and Honda models listed? A: Yes, it is offered as a replacement relay for both the Yamaha Warrior YFM350 and Honda Fourtrax 300 TRX300. Confirm your machine's connector style and terminal count against the original relay before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
