I'm repowering and replacing the guages.The fuel guage is working along with the volt guage.The tach won't do anything.I have trie the dial on the back and it won't do anything and was wondering if there is a way to test a tach.
Thanks Jerry

There is a "black box" that can test them but I can't remember what its called. A tech at out local BPS showed me one years ago. Is your motor charging the battery OK?
