Symptomatic issue:

→ ATV is presenting some cracking sounds from the cvt case and belt

→ ATV is running when idle even if you put on Neutral

ISSUE #2 – POWER STARTING RELAY

This Starter Relay / Starter Solenoid applies to ATV from 250cc to 600cc electric start engines. This relay operates in the same way as other non-fuse based relays, and using a 20A in- fuse is one of the best ways to provide additional circuit protection. Bolt studs are 2 cm apart centre to centre.

Most commonly used for (but not limited to) CF Moto 450 or CF Moto 500cc and CF Moto 600cc ATVs or UTV (4×4/2×4 and similar variations).

The issue with this one is that because of the sand, dirty or water it goes also to oxidate and can also burn your fuse or entire body of this relay.
