I just tried to reconnect my hood tach after being disconnected for almost 2 years. There are 3 terminals. I tried them all and the only way the tach light comes on is the way I have it connected. The 3rd terminal is going to tach terminal on distributor. Tach lights up but does not work. I ran 2 different wires and neither one works. Is there a way to bench test tach? I do not have any other old cars to try it on

Hi Rick, on mine I have one wire going to HEI, one to ground, and one to my fuse box (switched) if that helps....
