stukinwa1978 Posted July 29, 2009 Share Posted July 29, 2009 Hello, I have a 72' CF 600 fire engine. The tach on both the pump panel and dashboard is not working. I attempted to trace the wires which go inside of a 1/2" jacket. The wire goes up over the transmission and toward the engine. It appears to terminate near the front of the engine around the oil filter. I am curious how a tach on a Mack is controlled. Also if anyone knows how to fix this. I am a new owner to this vehicle and am just starting to learn my way around this vehicle. Thanks, Jared Quote Link to comment Share on other sites More sharing options...
