[urq] Intermittent no start, now a weird intermittent start.

[Schaible, David]

Check your voltage once started it should be over 13v at the battery if your alternator is ok, my batteries are usually 12.6 when fully charged.  If you have good voltage check your main ground connection and battery terminal connections.  You should be able to bring your battery to a shop to have the amp draw test done to see if it's still good, also you can swap in a known good battery to see if the battery is the culprit.  Many people insulate the solenoid on the starter and/or the very near exhaust  to minimize the effects of heat on the starter.  But with a brand new starter you should be ok for a while.......unless you really baked it with high exhaust temps for a while on a spirited drive.

Subject: [urq] Intermittent no start, now a weird intermittent start.

Sometime ago I put up a series of posts about an intermittent no start where it sometimes would start fine and sometimes I’d turn the key and nothing would happen, not even a click. However if I rocked the car a bit whilst in gear, it would start. Not only was this a pain when it happened it was a bit embarrassing too. I put up with it for far too long.....because it was intermittent.
Anyway after getting it all back together and up and running following the head gasket job I resolved to purchase and fit a new starter motor which I did today. (had a day off work quattro day in the sunshine!).
Now the new starter turns every time and whirrs nicely like a starter on a modern new car but..........after initially starting reasonably well the next time it turns slowly like the battery is run down and doesn’t fire. So I charge the battery up which surprisingly didn’t take long so it couldn’t have been too low. This time it fired up. I went for a short drive, came back, switched off. 5 Minutes later tried to start it and it turns over slowly like low battery but won’t start. Battery showing 12.33v and when I put it on the charger it shows fully charged. I am not great at diagnosing electrical faults. Fine at repairing them but not good at identifying them.

Anyone have any ideas what’s going on. Sorry to be monopolising the list at the moment but having a beautiful car and wonderful weather.....yes that’s right wonderful weather in England...I’m really disappointed not to be able to be out enjoying it on the open road. So if you have any ideas, as usual, I will be most grateful. Many thanks.

All the best

Keith
