    I have a 96 Civic DX and the other day my tach just died. It's at zero and hasn't moved since then. I checked the wiring for the power source going into the gauge cluster, that was fine. Then I checked the tachometer signal wire (blue wire going to ignition control module) and there was voltage on that wire too. Could it just be that the tach is broken? BTW just before it went to zero, the needle was jumping eratically and then it went down.

    Anyone have a clue to what the problem might be?

    does your car run?

    if it doesn't run, I'd bet $5 the ignitor (ICM) module in the distributor is cooked. It's a very common problem.

    The car runs fine actually. I'm seriously thinking it's the tach that's just broken, the wire is well connected in the distributor, the ground is fine, and there's current in both the power source wire and the ignitor wire.

    I'll get a new tach soon, it's not a big problem, it's just annoying that it doesn't work.
