If everything keeps going like that then it sounds like its a problem with the onboard computer. The computer controls all the guages and would explain why they all fail at the same time.

SOURCE: my tachometer does not work.

Look on the back when you have it out, are the 1 or 2 little "burnt" spots? Get some solder, flux and a solder iron, and put a tiny bit of each on the burnt spot(s).

SOURCE: 1988 Ferrari 328 gts tachometer quit working.

i have had the same problem...another tach. could not be found... find an electronic expert that can take a look at the platin behind the tach. it´s easy to demount...you will most likely find one of the hair thick connections broken through the years of vibration.  if you are lucky the one inspecting the platin can also micro solder and repair the fault... and you don´t have that big load of questions when cruising with someone..."is the tach. broken!?" and youn don´t have to rely on your ears when shifting.

My 1981 corvette tach quite working how do I get working again?


1981 Corvette has an electical tachometer that is driven by impulses from the distributor. First, check for blown fuses, next make sure the tach wire is plugged into the distributor. Next bypass silver tach filter or capacitor located by manifold to see if the tach moves at all. If these steps do not reveal a change in tach operation, then the most obvious next step is to remove the tachometer and get a new board for the tachometer. Unscrew and remove cluster lens and then unscrew tach bezel, and gently pull out the tach noting position of insulators. I believe these boards are available still at local autoparts locations. Replace board, note position of insulators and reinstall tach, bezel and lens. Old corvette are cool and are pretty easy to work on! Should be fixed, enjoy!

1991 nissan 300zx tachometer in cluster not reading while running


The blown fuse is an indication of a short in that circuit. Most likely it was in the tach portion of the circuit causing the blowing of the fuse. Other circuits will pass through this fuse so simply replacing the fuse restored the other circuits but not the bad one. Get a schematic and trace the tach to that fuse you replaced.

Tachamererter intermit dont work


Tachometer failures are very common on this brand. The tach will tend to hop around first and then just stop.
The most common failure for this concern is a faulty tach in the instrument cluster. This can be checked by using a scan tool to observe the instrument cluster data for the r.p.m. signal, if the scan tool shows a tach signal (RPM) signal then the instrument cluster isn't displaying this signal and is faulty and needs replaced or repaired.

Hope helps.

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.

Tachometer is not working


please rate highly if this helps.

Check fuse #37, 10 amp yellow in fuse panel on dash.

The camshaft sensor in the distributor sends the tach signal to the instrument cluster. wire is BU = Blue?
