Hi all, this has probly been discussed before, but here goes. Workin on my 2 roll over TB to 1 project. Before I started the work my tach gauge did not work. After replacing fender, hood and door, all the gauges but temp, stopped working. I know the tach was probly a stepper motor, but would the rest of the steppers stop working all of a sudden? I just replaced the battery ( getting bad ). That didn't help, checked all the grounds under hood, all good. Any suggestions. I will post pics of the project when I get the gauges working.
