Well, tachometers are a constant PIA. Sometimes they work, sometimes they don't. Sometimes mechanical, sometimes electrical. Mine are what I call "intermittent" performers. One of the last things I will try to cure again, and again, and again.

Subject: [diesel_mercedes] Tachometer Amplifier...Cigarette Butt Bust
I have a bouncy tachometer and one of the things that seems to work for people (at least temporarily) is the "cigarette butt trick" where you put the filter end of a cigarette inside the housing to provide pressure on the loose contacts.
Well, I found a cigarette butt (who knew THAT would come in "handy"?) while removing the console (scary stuff down there) parts to get them clean and remove switches etc. So I thought I'd give it a try, but no luck.
My tach barely registers AT ALL now. So I guess my options now are:
1) PAP find (wish me luck!)
2) and/or ground the cluster ($10 for a grounding cable shipped, or DIY)
3) $54 shipped electronic tach amp http://mbelectronicupgrades.com/Tachometer_Amp.html
4) used on eBay (currently one for $90+s/h)
5) new @ $135 (or higher)
I'm not having much luck lately...here's to that changing...
