Tachometer Broken

07-31-2009, 01:28 PM #1I have often read on this forum that Tachometers are an issue and usually dont work after a while. Mine hasnt worked in the last 20,000 Miles and I sould like to fix it. It sometimes turns on and works properly for a minute or two and then the needle drops and it quits. What would be a typical problem with this and what can I do to fix this without buying a whole new Tach?
Another option is to contact techguy512 and buy his $45 amp replacement.

Its a round black cylinder on the left fender by the glowplug relay. Unscrew it, pull the center part out and put a piece of cardboard at the top. That often will push it down enough to make contact again.

I know this is no real help, but the car has yet to leave me on the side of the road... so I keep the critical stuff going and leave the intermittent Tach alone. And it puts a smile on my face when it works for that 5 minutes each month.
I have the same problem with mine. So far I pulled the plug apart, cleaned all the contacts, gave them a gentile squeeze so they are oblong (tighter fit to Tach Amp), and pulled the Tach Amp cap off and put cardboard up there. No real change. Next I cleaned all the silicone off of the top of the Tach Amp and re-soldered everything under a microscope. It now works about once a month.

I never get that lucky. So how many quarters did you use?

It worked well and then the thing started to smell like burning plastic because of it so it took them out and in my frustration i jammed the plug in and tightened till is almost stripped and its worked excellent and accurately since
