Vauxhall Zafira duelfuel 1993 - starter motor burns out every year - why?? - frustratedzafiraowner

Can anyone help me- my starter motor has burnt out every year for the last four years. This always happens when I am driving- never when I go to start it in the morning. The first two times Vauxhall replaced the iginition switch as well, but that didn't seem to improve matters. The key itself has always worked fine. Last time it happened my mechanic replaced the starter motor with a Bosch part, but a year later it has happened again.

Seems very strange I think I have only replaced one starter motor in the last 20 years. Have they tested the old motor off the car? if not I would suspect the problem is related to the starter but I doubt if it was the motor every time - unless the starters are known to be problematic, I'm sure someone will tell us if so.

I'd be having a good, hard look at the engine earthing strap and where it attaches at both ends, ensuring that it's both in good condition and has good, corrosion free, metal-to-metal contact in both places.

Occasional short circuit in wiring from ignition switch to starter motor?

check starter motor ring gear, may be burred causing starter motor to stick in and be driven by engine thus burning the motor out
