Can someone give me the link of the thread that described which capacitors inside the tach need to be replaced to keep it from jumping all over the place.

i thought it was the springs that needed to be adjusted in order to stop the bouncing?Caps sound more feasable though

Is there no one who can help me out with this?

I'm guessing that it is just a matter of replacing some of the electrolytic caps inside the tach. I offered to do some research on this a few years back to see if I could come up with a fix - the offer was for a few people to send me their bouncing tachs (I would pay shipping), and I would see what I could come up with. If I could successfully come up with a fix and repair any of the tachs which were sent to me, then I offered that they could have them back - they just had to pay the postage both ways and parts costs.

Nobody took me up on the offer.

I don't think anyone has an official fix except to send it to PA Speedo and pay $180 for a new circuit board.

IIRC, it's a resistor that can be applied externally.
I saw it in "up fixen" I think.
I'll see if I can root it out.....it could take a while.

There was some discussion on tach bounce here but nothing to really correct it.

I think that PA Speedo would be the best way to go.

Yep I have the fix...toss it for a autometer monster

IMHO you need it for that bad boy your building and it's a 100 times better tach. Fits the stock hole perfect.

will the sportcomp guage work with our stock wiring?

If it matters, my tach bounces a LOT less now that I'm running a Crane Optical points system and their box/coil. Might have something do do with it. Anyone have a bouncing tack that's using a Mallory or any other dizzy?

No problem on the tach, I put connectors on it so I didn't have to cut the stock wiring.
Little bit of black RTV and stick it in.

The issue is you lose the turn and high beam lights. I got a couple of 12v mini lights from radio shack and did a stelthy install in the e-brake light lens. You could just drill a couple of 1/8" holes in the panel.

Thing is as solid as a rock and no more

if somebody sends me a tach i can figure a poor man fix, or even a new board. i would sell the fix for 5 bucks or the board for a little over cost. but my tach does not bounce so i cant use mine for a test.
