Covans Sending Unit w/ Autometer Speedo Question
I have the Covan's Classic instrument panel with the Autometer Gauges. Currently having some difficulty with the calibration/operation of the Autometer Speedometer.
I purchased the two wire speed sensor directly from Covan's. It has 2 wires coming from it, 1 black and 1 white. These 2 connect to the 2 wires leading to the dash harness. Those 2 are purple and yellow (twisted pair, purple is signal and yellow is ground).
My question is which wire from the sensor is "signal" and which one is "ground"?? I assumed black was ground, but my speedometer isn't working. It'd be easy to switch them around down on the transmission, but I thought I'd check here first....
Any one else with the same setup?,, could you let me know which wire is which off the sensor on the tranny???
