My tach just stopped working out of the blue (Page 1/1)
Fiero Thomas MAY 31, 08:03 PM
I have an 87 GT 2..8 and the tach just stopped working for some reason. Is there a common issue that there a solution to. I have a WTB in the mall for another one.

Thank You
Thomas

You can get it rebuilt by forum member J Gunsett.

Tach filter is likely dead. Temp test is bypass the filter to see if tach works. don't leave it bypass or can kill the tach and/or the ignition.

Dash plugs on back and/or clips on dash back can be crappy.
Tach has bolts that are contacts that get loose dirty or both.

Take tach out.
Carefully loosen then tighten all the bolts and stamped nuts a few times to wipe off minor crap.

I have looked through the system and the wire has come off the tach filter. it is to close to solder on the wire so I head to the mall.

Thank you all for your responses.

I have had similar issues with the tach and the rpm gauges when going through puddles or having the car being rained on/snowed on then having the car sit off. It usually fixes its self after driving a little bit luckily. Not sure if it is the same case for you.

Put the new tach filter on today and everything works as it should. Only issue is that I cannot get the bolt off that the filter is mounted to. I had to tuck the filter on so I hope it will be OK for a long while.
Thanks to mrfiero for the filter.
