Year 2000 P38 starter motor

Paul Coddington · Jun 23, 2023

Evening All.
I've had an issue today where a 4 month old starter motor became an ex starter motor.
It was on a year 2000 P38, 2.5DT, after a few stops earlier in the day, I came back to it and there was no response to the key, all the other systems where working fine, except for the starter.
After a lift home from a nice guy on a recovery truck, I removed it and took it to a guy locally who's a font of knowledge, he tells me that the starter was permanently engaged and had been ruined.
It's gone for warranty inspection and it's a possibility that they (Bosch) could say it's a problem external to the motor, possibly the vehicle wiring.
Has anyone had similar happen to them?
Also has anyone had to rewire a P38 starter from the key switch to the motor and what would be involved. Is it a case of replacement of the back of the ignition key and replacing any relays, or is it much more complicated.
Thanks in advance

On my dozzle i had it trying to start its self on its own when it was all locked up, i unbolted the the wire from the ignition switch off the starter and bolted it to a new wire that i ran to a switch in the cab and back to the stater to stop it happening again i was on holiday at the time with limited tools so it was a get home fix but has stayed that way just means you have to engage the switch as you turn the key, i used 25amp cable and switch

You can get a second hand one off the Bay pretty cheap as they almost never fail. Make sure it is the Bosch one. I think the Lucas one off the v8 will fit the diesel autobox but it certainly won't fit the manual one and the Bosch is a better unit anyway. Simple enough to swap over - just make sure you don't reverse the wires or you'll be back where you started.

As Keith says check for duff relay first

Thanks everyone. I've ordered another starter, which is arriving Monday. I'll change the relay as well.

Water and electric components are not usually friendly
