It was not hooked up with the old wiring, so I don't know if it worked or not. I read a tech tip on stovebolt -
http://www.stovebolt.com/techtips/electrical/voltmeter/So I'm thinking my modern alternator is too much for the old amp gauge, but I really have no idea.
I get little to no movement out of the gauge. It's wired per the instructions from Bill at Hot Rod Wires.
