For Honda Rancher 420 TRX420 FA FE FM TE TM Starter Relay Solenoid 35850-HM7-000

Starter Relay Solenoid for Honda Rancher 420

This starter relay solenoid powers the electric start circuit on Honda Rancher 420 ATVs, cross-referencing OEM part 35850-HM7-000 for exact fitment and reliable cranking.

Overview

This starter relay solenoid is a direct replacement for Honda Rancher 420 models, delivering the heavy current needed to spin the starter motor. The starter relay solenoid cross-references OEM 35850-HM7-000, so it slots into the factory harness and terminal layout. It suits riders and shops repairing a no-crank, click-only, or intermittent starting issue on their machine.

Specs At A Glance

Good To Know

Q: How do I know the relay is the problem and not the starter? A: A single loud click from under the seat with no crank often points to the relay, while a slow or grinding starter points elsewhere. Testing the small trigger wire for voltage while pressing start confirms whether the relay is getting the signal.

Q: Can I install this without special tools? A: Yes, basic hand tools are enough to disconnect the battery, swap the relay, and reconnect the terminals. Match the wire positions to the original layout during removal.

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