Tachometer and Odometer Just Quit Working the Other Day. Anybody have any ideas? I was Thinking a Fuse of Some Kind. But, Really Doubt it Would be that Easy for Somebody to Pull a Fuse and Disable the Odometer.
Thanks in Advance

The odometer is mechanical. It's run off the speedometer cable. Gear driven.
You have to open up the instrument case & remove the speedometer to have a look.
Tach is electrical. there is a trouble shooting procedure in the FSM, but honestly I don't know much about what the input signal should look like.. Output should come from the ignitor.
Does your AC still work at low RPM? If so, your ignitor is probably producing signal and you've got a jacked up tach (or connection)
If you need a spare tach only, I think I have one.

I have a similar issue. The speedo and tach work, but the odometer quit.
If I undertand the earlier post right, are they saying the speed and odometer are run on the same cable? What would make one work and not the other if thats the case?? Mines a 93 instead so maybe its different?
