Question about 1995 Oldsmobile 88
When car is running, the alternator big connection has only 12 v. or less. Alternator checked out good at autoparts store. I think Someone has miswired the lead going to the regulator when he replaced all the lights in front of the car. There is only one red wire going to the regulator, the plug has 4 prongs, 1 big and 3 small. I measured, but there is no voltage on the regulator wire whether the car is running or not. I think something has to energize the alternator through the reguilator for it to charge. Is that true? So there has to be some voltage on the regulator prong? But I don't know where is it wired to.
Joe, there is no longer a regulator on this car as we would know it to be. The ecm is now also resposible for telling the alt when to turn on and off. This was done in order for the alt to be turned on and off in conjunction with the other loads and engine speed in order to be more efficiant in the long run. So from what I read here, you either have a bad wire somewhere or your ecm is toast. Replacing lights-unless for some reason the wires were cut(doubtfull) would have no effect on the alt.
