Sorry for the long post... just wanted to give the full story. About a month and a half ago I was having problems with my car not starting. Got the battery and alt tested and the battery was determined to be trashed. Got a new one. A week after that, my car won't start again. Wiggle the negative battery cable around and it works fine... for awhile anyway. No problems for a month. Wednesday I left work and went to my friends and shut it off and when I go to start it again it won't even crank like before. Borrow a wrench from him and move my negative battery cable around again. Car starts. Get out into a busy part of the city and I'm sitting in a left turn lane without my turn signal on, without my heater and rear defroster on, and my radio on at very low volume and everythings fine. A couple seconds before the light turns green, my lights dim, alt guage drops, RPMs drop, everything goes dead. Won't crank again. Pop the hood and move the cable again and it works! Not another problem till tonight. Started right up but as I got close to home my alt guage started pulsating and jumping all over and my headlights were getting really dim. I had my stereo on a lil over half volume which usually never does anything to the guage and RPMs were about 2k the whole time the guage was fluctuating. After I noticed the large fluctuations (sp?) I shut my stereo off and it became a little more tame but it was still bouncing all over. So... I prolly need to replace my negative battery cable and I did a serach so I'm guessing I need a new alternator too? Once again sorry for the long post. I'm just hoping I don't have to spend much more money right away.
