I am having a tough time with my DeLorean's electrical system. The case is- my regular Motorolla alternator is producing only 10.5 volts shown on the gauge constant. Constant meaning-When I am to put on my headlighs or my fan (heat/AC) the voltage will drop down. The problem is-with my headlights on and the gauge running well below 10.5-I cannot accelerate there simply is not enough power to run my headlights and run the engine at the same time hence there is a power drop in my motor which comes immediatly back once the lights or whatever is on is shut off. My thoughts were a bad alternator/battery/contacts/etc. Now I have come across something that stumps the hell out of me-whenever it rains and i drive the car, the gauge will show a constant reading inbetween the middle 13, and the orange lower mark-it is about 12 or 11.5 volts. At this reading with my lights on and even my fan on, my engine still has enough power to run good at higher RPMs. With this, I figure the water is creating a ground-so I must have a short somewhere. If anynone can suggest a place to look a place to start-or maybe you have had a similar situation which you fixed-I would appreciate to hear what you have to say. To clear up more on what I already tested-I ran the engine and unplugged all the fuses that wouldn't stop the engine from running-still 10.5, also cleaned up alternator contacts aswell as starter contacts. I was considering the purchase of a 150 AMP alternator from Specialty, but if I can fix my current problem, I could really use the save of almost 300 dollars. Alternator has new brushes etc. thanks again for the help guys--Dani
