My alternator was original from 81, and after all the years it finally started to die about a year and a half ago. With my headlights and heater fan on during driving, I would have poor acceleration until I shut something off, that's how I knew mine was going bad. I could be going up a hill with everything on and have poor performance; when I shut something off (fan or lights), then the performance jumped right back into normal performance, actually made the car shake when it came back to normal from being bad. Anyway, it could be your alternator, or just a bad contact on the main wires to the starter, grounds etc check those out. Replacing the original alternator is something you should look into; because if it hasn't gone bad yet, it is likely it soon will. -----Dani B. #5003 To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
