The other day the battery died so i checked into it and I replaced the alternator...like anyone would,, the battery is almost new.... I put in the alternator myself (Pretty easy actually ) I started her up and it ran fine...as soon as i rolled out the driveway and moved about 500 feet the alt light came back on and at the corner store the car died.... Yesterday I replaced the alternator again and the darn thing did it again...its like the alternator voltage regulator is blowing on me ..... WHY????? Can you please advise me on what could be the problem...I recharged the battery 100% Is there a module somewhere that i need to change?? Please help me _Viper_ This post has been edited by _Viper_: Mar 16 2008, 08:36 AM

Can you get your alternator load tested? We have auto parts stores in the US that will load test the alterrnator in the car, and on the bench as well for FREE. Can we assume that the battery cables on a 1993 Scoupe are in good shape? These are cheap to replace if needed. how about the connections on each end? Are they clean, shiny bare metal to bare metal? Lastly, perhaps first, any blown fuses? Not just for the alternator, but you may have a big current draw from a short somewhere. If you alternator passes the load test at rated capacity, your car may be pulling more amps than the alternator can generate. Byron

Byron [right][snapback]143908[/snapback][/right] Well you are soooo right on this... I took my battery into my house and it was at 30 percent on my digital charger.... I suspect that the battery was so dead that the voltage regulator would cut out to protect the alternator... I reccharged the battery for 5 hours and bigo everything works like a charm... Thanks it all makes sense now lolll
