While I was swapping carbs from a Holley to an Endlebrock and changing all thing associated with it the tach just quit. I happen to glance at it while it was running to set the idle and it just stopped cold. I have checked fuses and tracked down the green wire on the coil and its all good. So what possible connection can changing the carb and starter solenoid (different story all together) have on the tach and how is it wired in? I am about to dive into the dash next weekend but before I go rooting around blindly I'd like some tips and advice. As always, Thanks
