ABYC Standards do not require overcurrent protection between the battery and the starter. By the time the fuse or circuit breakerís rating was high enough to handle the temporary load of a starter motor it would be to high to provide any usable protection to the wire.

Thanks for explaining the neutral switch, I couldn’t understand why the relay wiring diagram does not show a power source. The one on the Perkins diagram does.

Starter inrush current can be well over 1000 amps, which would be a problem for most fuses. Ergo bingo, no cable protection for starter motor circuits.

Don't believe everything that you think.

Mechanic needs to stop replacing things and to use an ohmeter and clampon dc current meter.
Did we establish what size breaker is tripping? And does it blow during crank or just after?
