I have a 1977 spider with dual points, in the last few days my RPM gauge is going crazy, fluctuating from 0 to 4000 rpm while driving 70 MPH. Car runs great no firing issues just the RPM gauge going crazy.
As per your opinions where should I start looking? Does RPM gauge works with the points or with the alternator.
Thank you

Re: RPM gauge issues
If the car is running fine, your gauge is probably going bad. Mine did that and got progressively worse in a very short period of time. Replaced the tach and all was fine.
