The trip meter and speedometer work fine but the odometer is dead. I took the assembly out, the odometer wasnt frozen and the motor for it seemed ok as far as a Ohm reading. I swapped it anyway with another used one and its still dead. It looks like both odometers feed from the same connections on the circuit board, so what am I missing? I can swap the whole board I guess, it just isnt making sense. Has anyone tore into it that far? Thanks all, John
Maybe the circuit board went bad? I had an odometer quit once but it was the motor. You could find a known good speedometer assembly, swap the counter/number part to the good speedometer and see what happens.
Finally got it working, I believe that the board was bad, and possibly the guage itself since it has 4 lugs and seems to feed output to other things. I couldnt just change either board or guage because my parts unit was 1 year older and didnt seem compatible. The 84 board was much larger than the 85 and when hooked to the new speedometer guage made it go crazy. Sorry I cant be sure for the rest of you with similar problems, but my gut is saying the guage and possibly the board were bad.
