Ford F834 Posted May 3 Share Posted May 3 There are two designs of tachometer… the integral circuit type from 85/86 that has an “open” exposed circuit board, and non-integral circuit type from 80-84 with a “closed” case covering the internals. General consensus is that non-integral circuit type tachs have a lot more problems and are more sensitive to sticking when cold. They also tend to develop problems when not used for long periods of time. Given the choice, I would recommend looking for an integral circuit design tach.

User811780 Posted May 9 Author Share Posted May 9 I give up, anyone want to do some shopping for me and point me in the right direction to a gauge cluster that would work with my setup??? Link to comment Share on other sites More sharing options...
BigBrother-84 Posted May 10 Share Posted May 10 I give up, anyone want to do some shopping for me and point me in the right direction to a gauge cluster that would work with my setup??? First, do you need the automatic transmission indicator? There are plenty, with or without this indicator, on ebay. I used the eBay criteria«1980-81 f-series bronco cluster tach» and got multiple results. Would say around 250$. Just be sure to avoid « diesel » or « 1980 » units. 1981 to 1986, gasoline truck or Bronco, should work. Red printed circuit behind. Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted May 10 Share Posted May 10 I don’t need the indicator, Any certain RPM I should look for? If you read the linked page you'll see you want a 4 or 6K tach, and NOT a 4,500 rpm one. Diesel tachs do not have a coil trigger to work with. 💡 Link to comment Share on other sites More sharing options...

Diesel tachs do not have a coil trigger to work with. 💡 I think a majority of used available gasoline clusters w/tach are 6000rpm model. That’s the one I installed in Big Bro (the truck didn’t have). Since Big Bro is geared as a farm tractor (or a battle tank), I rarely reach 3200rpm. Link to comment Share on other sites More sharing options...

Yeah, well how many do you think were* Windsor's and 460's v/s how many 300's, which would use the 4k tach??? 🤔 *damn phone... 😖 Link to comment Share on other sites More sharing options...

Really? Link to comment Share on other sites More sharing options...
