The starter relay solenoid is the high-current switch that connects the battery to the starter motor. A small control current from the ignition switch energises a coil inside the solenoid, the coil pulls a copper bridge across the two heavy studs, and the starter draws the full current it needs through that bridge. It is the busiest and hardest-worked switch on the machine, and burnt contacts inside it are a very common cause of a quad or cruiser that clicks but will not crank.
This is RMSTATOR part RM09016, a brand new starter relay solenoid switch engineered to surpass original equipment specifications, with every unit tested before shipment. It is a cylindrical two-terminal, two-wire unit with a single plug, 50 mm tall with a 35 mm outside diameter and 55 mm between the centres of the two fixation holes, so it bolts into the original bracket as a direct replacement requiring no modifications.

Frequently Asked Questions
Does this solenoid need any modification to fit?
No. RMSTATOR describe RM09016 as a direct replacement component requiring no modifications. The two-terminal layout, single plug and 55 mm fixation hole spacing match the original unit.
What is included?
The product ships as a single starter relay solenoid unit, tested before dispatch. No additional hardware or accessories are listed with this part number.
How do I know my old solenoid has failed?
The classic symptom is one loud click, or rapid clicking, from under the seat or beside the battery when you turn the key, while the dash and lights stay on. Burnt internal contacts can also make the starter turn over slowly or engage only every second or third attempt. Check the battery and both battery cables first, since a poor connection produces the same click.
What precautions should I take when fitting it?
Disconnect the battery before servicing, and have the installation carried out by a qualified technician to avoid a malfunction. The heavy positive cable is live at the solenoid stud even with the ignition off, so removing the battery earth first is essential.
