I am running two 37 amp radiator fans. When the fans kick in, my ammeter goes from -0- to 45 amps and stays there at all speeds. Fortunately, I have a kill switch on the fans so I don't drain the battery when the car is turned off.

The alternator is a single wire unit, so there is no regulator.

Here's the question: Is the problem the alternator or the battery, or something else? At this time, I cannot tell you the rating on the alternator or battery. However, what should they be to handle the draw from the fans?
