juxsa Posted March 19, 2018 Share Posted March 19, 2018 1978 280Z tach issue with SU carbs and GM HEI My tach isn't working. I have confirmed that the solid blue wire is hooked up to the negative terminal on the coil and that in the passenger floorboard area the resister is hooked up to the solid blue and the blue/white wire. I currently have the hazard switch unplugged and also have the stock ignition box un hooked. How should I confirm that the tach is getting signal and power? Which colored wires that the tach plugs into should I check to see if the tach is getting power? Thanks Quote Link to comment Share on other sites More sharing options...
