Starter too hot - wont work?

[KiwiKommy]

My VK 202 EFI has an intermittant fault that has us all puzzled.

Start the car cold no worries and go for a drive, get the engine up to normal operating temp or a bit warmer and stop somewhere (shops, servo, what ever) and sometimes she just wont start again!

The lights on the dash come on and everything else is normal but turn the key and nothing happens. Get a jump start from someone else and she starts no worries!

It has not happened to me, but has happened several times to my wife, mum-in-law and dad-in-law. Now my poor old girl has a bad rep and they wont take her anywhere

We have this theory that the starter motor is naffed or part naffed and and when it gets too hot (sitting beside factory extractors) it jams or fails to work, but get two batteries worth of kick and fires again..

We have been through all the other possible faults and eliminated them as eye witness acounts from servo assistants jumping car or other people who have bailed out the in-laws when she died mention odd noise near starter...

Do you think my starter is getting too hot and jamming??

Yep. The armature is rooted. When it gets warm, the electro magnectic field that spins the motor isn't strong enough. Get another starter.

HMMMMMMMMMMM
sounds bout right for a dead starter,i would go and buy a new bosch reduction drive one from repco or bursons,chances are ya gunna have to drop the manifolds off to get the old one off.

On the EFI engine, I'm pretty sure you can get the starer out without removing the extractors.

We had a similar problem a while ago with a new starter. We put exhaust wrap around the extractors to give it a bit of a heat shield. No problems after that. Might help.

I beg to differ...
I reckon you should fit a starter relay... OR if it has one, check the condition of the wiring...

to prove this correct next time it wont start when hot, turn the ignition on and get under it and short from the heavy battery wire post on the starter to the terminal where the purple solenoid wire goes on....if it cranks and fires this way then I'd say its just not enough voltage getting to the solenoid...
