I have the same truck.   The instrument cluster is a sealed unit that is not repairable by mere mortals.   You might want to check the large plug-in connector on the back and see if it is partailly out, although that's not likely.  More likely is that there is an electrical short in the cluster, and it will have to be repaired.  Your dealer can send it out, or there are a couple of independent shops that you can find on the web to send it to.   I lost the LED's in mine and had to send it out.   It's really easy to get out - just pop off the front trim that goes around the instruments and the radio/climate control and take out the couple of screws that hold it in.  Make sure you disconnect the battery first.   Also, it's easier to get out the trim if you start er up, keep your foot on the brakes, put the shift level all the way down to the right, then shut the truck off.    Hope this helps.  > Joe

If you replaced the cluster, the tach was replaced. So its probably not a problem with both the old and new tach. Its probably a problem in the wiring to the tach. Put a multimeter across the tach signal wires on AC setting, rev the car, does the meter reading change?

How to wire up factory tach for 70 ss chevelle with gauges


The original tachometer was powered from the negative side of the coil.
I don't know how many wires you have to work with, but the one that powers the tach should go to the pigtail wire on the harness for the coil - dist cap.

Tachometer stopped working completely but all other gauges are fine. Tachometer would work off and on for a few days before completely not working. "Check engine light" stays on. All fuses are fine. This...


It's very UNLIKELY the jumpstart had anything to do with it, unless you accidentally connected the battery in 'reverse polarity', which causes the electrical system voltages to 'DROP' instantaneously to near zero volts and create 'current spiking' in all active circuits. Nevertheless, the microcomp in the instrument cluster which drives the TACH has protective curcuits. The only solutions are to eliminate any problems in the wiring between the ECM/PCM and the instrument cluster, and bench test the tach to determine if it's working properly. Process of elimination - if wiring is ok and the Tach is ok, then the problem is in the ECM/PCM.

Instrument cluster says " Service 4 Wheel Drive". No 4 wheel drive while this is on.
