OK so I’ve been having a charging issue in my imperial for a while now and I’m trying to straighten it out. At this point it has me a bit baffled, The alternator that was in it I had tested and it failed so I bought a new one and installed it in hopes that this would solve this problem. With the battery fully charged I can’t get the alternator to put out over 12.2 volts. I get the same reading whether I am testing the output voltage at the battery or at the alternator and I have checked the resistance across all the grounds in between the battery the engine and the chassis. I also have taken the mechanical voltage regulator out of the equation with no change. I even went so far as to put the known good alternator from the Challenger in it and have the same result. I even swapped batteries and had no change in the situation. What am I missing here? Basically I can take the car with the battery fully charged and drive it over a period of several days and the battery slowly discharges to the point where it needs to be Recharged.
