Hey, I have had my 997 since October and the battery went dead after not driving it for 2 weeks. I checked the voltage and its at 12.8V running.

I'm leaning towards the battery cable, which is a known issue! The battery was replaced right before I purchased the car. So I know that is good. I still need to check at the back of the alternator to be certian.

Has anyone replaced this cable themselves? I searched and there are price quotes from $280-$900.

Thanks

 

Good question. I think you need to pull off several panels under the car.

 

Check renntech.org maybe Loren (moderator) can advise you on DIY'ing the job.
You want about 13.6 - 14.5 V running I believe. I'd check the output at the alternator if you can get at it. Good luck.

 

A lot of discussion on this topic on Rennlist:

It should be 12.8V wit the car NOT running.

 

I'm extremely handy with cars and have rebuilt/restored plenty of things with wheels. I'm just curious as to the complexity.

 

sig65, you ever end up doing this? About to do it myself. I haven't looked at it, but I imagine airbox + intake mani removal will do it.

 

I image the real work begins. I haven't found any write up's on this either, searched Rennsport as well.

 

just replace the battery and everything will be fine
