I recently purchased a 1999 9-3 and I am in the process of getting it ready for driving. I find the battery runs down to 8-10 volts while sitting in my warm garage. I had the battery checked at a local part store, and I removed the alternator and had it checked my by favourite alternator rebuild shop. Both were OK. I trust the alternator shop, but the auto parts store is questionable ..
After sitting for a week or so again in my garage I went to take it out and the battery was at around 8-volts. I put my charger on for a couple hours, brought it up to 12.5volts and it started. I ran it on the driveway for 10-minutes and the car started to stall and the lights were almost gone .. .. again the battery was back to 8-10 volts..
There isn't a volt or amp gauge on the dash, so all I can rely on is the alternator idiot light that goes off when the car is running.
I am going to pickup another battery and I could go through pulling the alternator but do I need to? I saw a note on a website about a grounding strap on the alternator... all I had was a small wire and the heavy one.. no ground straps..
Any ideas??
