2002 turbo......

This is now the second time this has happened:

Get in the car, depress clutch, turn key and all I get is click, click click. All the interior lights still light, the radio comes on, etc (i.e. all electrical equipment seems to be working...). Still enough juice to pop the hood and access the battery. The voltmeter on the dash reads about 10-11 volts. Turn the key off and try again and same thing...

The first time it happened, I was in a hurry leaving for work--so, I hooked up a battery charger/jumper and the car turned over with no problem . Got to work, put the car on a charger and within 30 minutes it showed a full charge. Sure enough, voltmeter with the key in the on position shows 12 volts, up to 14 with the car running.

Same thing happened today, about three weeks after the first incident. This time, the battery jumper didn't start the car right away--I had to let it charge about 5 minutes. Again, before jumping the voltmeter read 10-11; after it read 12 and up to 14 running.

I have noticed that the car does lose electricity during these episodes, if briefly. I know because I have a Kenwood stereo which loses all its memory presets when this occurs.

So, any ideas? Sorry, I know this is long but I wanted to include as much info as possible. Wouldn't seem to be that it's the battery, or is it just going bad slowly...? Starter switch? Alternator? Help? Thanks!

Sounds like the battery is going bad...it will take a charge but won't hold it. It shows 14 volts while the alternator is putting juice in it but wont' hold the charge. Have it load tested.....but I'd start with a new battery first.

Thanks, guys. Guess I'll be looking for a new battery. The RennTechers and the 6speeders all seem to be in agreement!

Yeah, I figured most of us were on the same forums...not everyone has the same screen names though. :D

I see you had about a half dozen or more suggestions for a battery over on Rennlist too! Considering this as a democratic society, I'd say the majority vote was for a battery.

Yes, democracy at its best! In fact I believe in it so much that I replaced my battery last night :D

If everything else is ok- have you tried removing your driver's side floor mat (or at least pulling it way back away from the pedals)? If mine is even just a TINY bit under the clutch, I get that same clicking and no start. I was about to have it towed in when I called my local Porsche dealership and they told me to try the floor mat first... sure enough, it worked.

If you have already done this, I apologize. Just thought I would mention it. Good luck! :-)

Hmmm...that does make sense... If it happens again I'll try that, may save me some frustration :huh:
