Hi Tony,
Yep all sorted except, my starter motor is making funny noises! so I removed it tonight and found that the nose is broken off that holds the bush for the end of the shaft !
Had a good look at it and cant see anything that could have caused it. Nothing loose and nothing loose in bell housing etc.
The numbers on it dont seem to come up on google except the solenoid number comes up but can`t id it from numbers on starter casing. Its a Bosch and for a 2wd Sierra Cosworth. I may get it rebuilt or even a new Powerlite depending on the deals out there. Need to sort before next weekend!
