my tach has been going really haywire lately, actually you could say that its been acting independently. sometimes it likes to stick at 0 , sometimes it likes to stick at 9k rpms, other times it just bounces around freely. i havent seen it read the actual RPMs for a while so i'm wondering if this is an electrical problem that can be fixed or would i need to get a whole new cluster?


thanks in advance

sounds more like the guage is dieing. i don't know the specifics but for some reason or another some peoples tachs just die out.

i dont think that the needle is sticking. it likes to bounce around a lot


the gauge can just die out? is there any chance its electrical? if the gauge did die out do i need to buy just the tach?

The crazy tach is a common electrical problem. There are (cold) solder joints on the tach PCB that like to break. You'll have to re-solder them.

I haven't done fix myself, but I think someone did a write up on how to tear down the gauge setup. Try searching for "tach solder joints" or something similar.

Yup, tach is dying. Mine did the exact same thing when it was on its way out.

I tried the resoldering thing, didn't work. Just save yourself the time and money, and find someone parting out a car and buy the tach. It's real easy to replace, PM me if you need help.
