Sounds as if your alternator is malfunctioning-not putting out enough voltage- maybe it is time to replace. I had similar problems with my DeLorean, I couldn't even drive at night because when I had the lights on it would drain so much voltage the engine had trouble accelerating. I got a new 130 amp alternator from SpecialTAuto and all my electrical concerns are pretty much over, I can drive at night with the lights, AC and everything else on and the engine performs nicely-gauge reads right around 12, sometimes a little lower, sometimes little higher. Have your alternator tested, then you can determine what to do next. Dan Benedek, #5003 > I was driving the car today with nothing but the A/C on and the voltage was really idling low. What can be done to improve this?< 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!
