Tach issues

[Pathmaster95]

When I bought my Pathy the tach didn't work at all. Since it is an a/t, it really didn't concern me that much. After having it a few days I took it out for a trail test, really just making sure the 4wd worked. When I shifted into 4 hi my tach immediately started working. After a few minutes I shifted into 4 lo and the tach quit again. When back in 4 hi it started working again but it would jump around occasionally. When back in 2 wd it will work for awhile then jumps around a bit then quits again. Occasionally when I start it up in the mornings it will work for a few minutes then quits. I figure there is a break in the wire somewhere. I would think it was near the transfer case shifter, but why would it even be routed anywhere near the shifter? Has anyone experienced this before and if so, where did you find the problem? Thanks.

That's weird, cause the tach runs off the ECU and the distributor. No tach wiring anywhere near the t-case or shifter. Check the ECU plugs to make sure they're not loose? Check the ground and wiring on the distributor, as well.

The 94-95 are prone to the tach giving up. Mine would jump around all the time when I got it. I just replaced it with one out of my old truck.

 

I couldn't tell you why it works in 4wd.

I don't know the 95s - is there an indicator for the 4wd system in the tach? If so, I am wondering if somehow that a loose connection/ground is being "fixed" while in 4Hi.

A working tach was optional in the 95. You had a choice between it or a working spedometer.

You could try a JDM swap, but then the gauge will read backward. Good luck!

sounds like you might have a ground issue....
