968parm

My 968 died on me right when I got off the freeway. Even with the jumper it wouldn't start, I put a brand new battery last month. So i just replaced a new battery but if i take the positive or negative off, the car wouldn't stay running. So is there a problem with the alternator, that it might be bad??

Removing your positive cable is the worst way to check if you regulator/alternator is working. The voltage spike could fry your ecu.
Take a voltmeter and see what are the readings when the car is running. Should show over 13.5 volts.

Removing either battery cable while the engine is running can almost instantly destroy the diodes in the alternator.

oh alright, that helps a lot. But the alternator seems bad so might have to buy a new one. Any idea which one I should I get?
