HI can anyone out their help me. I own a 1994 Sunvoyager pusher on a Spartan chassis with 5.9 cummins td and Allison AT520 transmission. My problem is the speedo has stopped working. Inspection at the transmission end today revealed that the 2 devices coupled together and connected to the tailshaft drive point had come slack and the securing nut threads damaged. One of the devices has a 2 wire connector and one has a 3 wire connector. Am I correct in that they are both vehicle speed sensors and if this is correct which one is for the speedo. The one with the faulty securing nut ( the 2 wire one) has markings which read 59D-02392-1 8 pulses per rev and rev c printed on the body in white. Does anyone recognise this and where can I get a replacement. I would also appreciate if anyone can advise on how I can fully check out all the wiring of the speedometer circuit.
does anyone have a circuit diagram they could e mail me. I live in Scotland
Many thanks in anticipation
