I bought a 140 amp (one wire hook up) alternator for my 91 LX 5.0 and hooked it up like a "3 wire" like it said could be done. But my darn battery light came on and stays on even though my volt gauge shows I'm charging just fine. I was wondering if anyone else has done this and has had the same problem. I'm sure I could just pull the bulb from the "idiot light" but if I have something wrong I'd rather fix it. Thanks in advance.
