M_Motorsports Posted June 23, 2017 Share Posted June 23, 2017 Bought a '72 Z and the speedometer is not working. Having disconnected the cable from the back of the speedometer, jacked up the car and found the end of the cable turns with the car in gear. There has been some rewiring due to the car becoming a ace car and there is no longer any wiring connected to the back of the gauge. Besides the original wiring to light up the gauge is there any other elec. needed to run the gauge or should it be all mechanical at this point?

RB26powered74zcar Posted June 23, 2017 Share Posted June 23, 2017 Cable only. Are you sure it was screwed into the gauge completely , as to engage the dial mechanism ? Quote Link to comment Share on other sites More sharing options...
M_Motorsports Posted June 24, 2017 Author Share Posted June 24, 2017 That will be my next step. Just wanted to know if elec. could be the problem. Quote Link to comment Share on other sites More sharing options...
