CURT - SDC Forum - Sept 2009 My amp meter flickered from zero charge to a small charge and kept repeating the same movement. The battery, alternator, and regulator checked out within normal limits. I took the car to an auto electric shop. Cured!! The wire from the regulator to the ignition switch showed high resistance. New wire and amp needle is as steady as ever. I might add this is with a Mopar alternator of early 60's design.
