83 SC won't start
So what's up? Just bought my first Porsche (1983 911 SC Cab).
I drove to golf this AM, got back in the car & drove home - all okay. One hour later car would not start - just a couple clicks from up front - no starter noise etc. - reset the relays at the fuse box (random guess because of the clicking noise) and car started right up. Went to get smogged - turned off car - restarted for the smog guy, but after smogging same problem as before - would not start - we pushed it to get it started and it started right up. Got home okay, turned off the ignition and then tried to restart, but no luck - same clicks from up front but no indication that power was getting to the starter - tried to jump start with a battery pack and would not start. The battery shows 12.35 volts. When connecting the negative terminal I got some small arcing and thought this not to be correct ... so what do I do now? Thanks for your help! |

Some additional info - after above post, I reconnected the battery pack and the car started right up! Only thing different is that I connected neg battery pack to chassis and not to the battery - also, another hour or so had passed since last start attempt - maybe something is heat sensitive? Or what?

I have this problem too. It could be due to the heat. Check on pelican for the starter relay kit. Its a fix, however, the cause has something to due with there not being enough current going to the starter when the components get hot. The ground strap is a place to start.
After some time the car cools down enough and then it starts again

Had the same thing happen to me recently - especially if you tried to restart after being off for only say 5 or 10 minutes. No clicks like when you get a low bettery - just silence when you turn the key, but with all the lights dimming like its trying to start.
Turned out it was the starter solenoid - gets stuck when its old with the buildup of dust etc. from the starter motor brushes. Had the starter reconditioned (much cheaper than a new one) and have not had an issue since. Tim

Thanks for the help!
What about the arcing when I reconnect the negative terminal to the battery - what is causing this? Or is this normal? |

I rarely worry about it though.
