Okay, about 2 months ago my original tach died, just stopped working while driving. So I checked all the plugs and connections and everything seemed to be plugged in, I replaced the tach yesterday with another stock tach out of my friends 83 GT, it is a good known working tach, and nothing.
I guess what im asking is there any fuses, circuit breakers, relays, etc in the tach circuit? or where could I possibly start looking? wiring colors? I dont really want to put an aftermarket tach in. Its just the Stock duraspark ignition system on my 83 5.0 Capri.
any help would be appreciated, thanks!
