Need some fast help re volt meter!
Getting ready to leave for 2 day DE at Sebring. took car to work today and volt meter read 11v. Car runs fine with headlights on and no alternator lights or anything. So I panic cause dont want a break down at the track and I go to the dealer. they say if no lights are on dont worry about it just go? I say ok see ya!
Should I have stayed and left the car to be checked or what? any ideas, maybe just a bad volt do-hickey?
TIA

Tom,
I would check the volts at the battery with the motor running. After giving it a rev you should see 13.8 volts minimum.
The DME will try to compensate for low volts but you will loose some go !
What a cr*p attitude by your dealer. A check would take 2 minutes and have you happy that they care !
All the best

Tom, I have heard on these forums about 1500$ installed ,but am not 100% sure. I sure would be upset with the dealer that sent you on your way thinking there was no issue. Cost of the alt aside, you wasted time and money at the track. Not surprising given the general lack of customer service at auto dealers these days. BTW, did you make it back from the track or did you need a tow. Kevin

Tom, I have the 06 Porsche PET on my computer, which is the software the dealer uses to find the parts on our vehicles and the 3 phase generator(altenator) is PN 99760301200 with a dealer list of 1098.28. Good luck. I am sure Sunset can get it cheap. Kevin

By chance you arent driving the car regularly, and it doesnt keep the battery charged as a daily driven car. So it will drop , even go dead. If you can start driving it regularly, it will charge back to normal. Or you can put the charger on it for several hours and it should look normal.

okbarnett, you are right I dont drive the car daily, it is more of a track toy for me and what you said is certainly correct and I appreciate the input. But my car is on the charger all the time so the battery wont go dead that is why I was immediately suspicous of the alternator.
And for the record in this thread, my alternator WAS bad. I was told gee not usual for "these" cars but "cars driven hard at the track at higher RPMs plus the heat may add to early failure"
Lessen learned was this.......when your volt meter reads low ah something is probably wrong and if someone says other wise get a second opinion!!!

Tom,
Hate to bring up an old and probably sore subject, but I'd like to hear what you ultimately did to replace your alternator.
See my other post here.

Rather than spend $1k on a new alternater........try you local auto elect. shop or yellow pages for a rebuild shop. This is old tech stuff and often it's in the control circuit (diodes or something)......here in L.A., I've had Porsche alternators rebuild for $50 while I wait. MK
