I had a diesel engine machine today, that someone had wired up a toggle switch from ignition live to the starter motor solenoid pull in connection, due to problematic sticking ignition switches.
Unfortunately, somebody connected the original starter wire from the switch, giving 2 wires pulling the solenoid in.
Eventually, the starter motor main motor burnt out.
Would the above cause that? Increased amps etc?
I'm trying to be 100% sure whether it was a sticking ign switch or the 2 wires throwing the solenoid in, that caused the burn out?
