Well I got tired of chasing resistance faults in the starter motor circuit,and added a start relay out of a worn out rider mower engine to the dong feng 204 tractor ,yes it does not look great straped on the starter,but it works great.So if you get tired of chasing high resistance faults with clutch switchs and light gauge wiring,do youself a favor and wire in a relay,I think you won't regret it.
