Tach For Sale? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

76HighSierra · 08-02-2004, 03:27 AM

Anyone have the tach only out of one of our trucks that they would part with? I recently installed a tach instrument cluster in my truck, and it seems the tach is bad. It reads WAY low and bounces. The rest of the instrument cluster and circuit board are perfect, problem is, these tachs are supposed to be non-serviceable. So, anyone with just a tach unit? I'm not concerned with what year, as long as it works properly.

marc, read the info I put into the other tach question about servicing them and it does matter what year to a degree because of the warning indicator window at the bottom, DAVE

Mine does have a little circuit board on the back, but I don't recall it having any red coating over the components. The cluster came out of a '76 suburban and was almost a direct drop-in on my truck ( after installing the tach harness, of course). Any clue whether it's rebuildable, Crossy?

yes that type is what i'm talking about being rebuildable. I believe they went to that style in 76. DAVE
