I'm in the process of doing a complete overhaul of the electrical system for my 69 SB: new wiring harness, alternator,& regulator. Just got tired of hunting down shorts and glitches, and whoever had the car before me has wires running all over the place (half of them not hooked up to anything!). Anyway, the question is: I'm replacing the alternator's external voltage regulator and coming out of the side of the thing is a single wire attached to a cylinder that is held in place by a metal bracket. What is this thing? Some kind of capacitor? It lookes pretty worn, so I might as well replace it along with everything else, but I need to know what I'm looking for first. Any suggestion on where to get one would be helpful too.
Thanks for any help.
