I have a VOM and a AC/DC clamp on ammeter. Or do I need to get a gauge that shows milliamps ? Thanks for any help. I really want to keep my old Bonny on the road. I bought her new and now have 187,000 miles on her. Thanks again, Gary
How old is the bateery? maybe pull it and have it tested at a parts store. Same with the alternator.
But if you have a draw you will need to put the VOM in line between the negative battery cable and the battery. Put the red lead on the negative cable and the negative lead on the battery. I would start by measuring amps. If you dont get a reading then switch down to milliamps. If is more than about 250 mA than you have a draw. If you have any add ons to the car IE stereo, video, amps etc, I would disconect those to start and see if those are the draw. If those don't do it than you would need to start pulling fuses to see what circuiot has the draw. You will need wiring diagrams to figure what is on each circuit.
