Speedometer Problems
1979 SC
Speedometer ran when I first got car, then had the transmission re-built (by Gary Fairbanks in CT) and two years rebuilding the engine etc... and it now doesn't work.
I got a new sensor, and just had my speedo re-built by North Hollywood.
I have continuity from sensor H wireattachment to the two brown wires at back of speedo.
4 wires attach to the back of speedo
1) have power on red/black when ignition switch turned on and attached to +
speedometer contact A is left empty
2) the green sensor wire goes to 31b and
wires 3, the other sensor wire and wire 4, a ground wire, goes to the - .
Could the transmission be missing whatever the sensor picks up?
Can I check the sensor ? Should there be continuity between the two sensor wires?
please help!!!!!
