There's no relay or fuse to check if the other gauges work.smokinLS said:the engine does run fine, i was hoping that the tach is bad. i took it out and am trying to find one in a salvage yard since ford discontinued it. if it turns out to be electrical can anyone tell me if and where there are any relays to check or where the rpms are read from, ie. distrib. or any other part.
thankx for the input so far
