Attempting to Fix Factory Tach & Gauges

This is the circuit board

There should be a ground wire on the 10mm screw that holds the dash in place under the hood release

You are awesome. I'm running outside to check and clean it now!

Proper voltage and a clean ground on all components. Do you have a ground strap on the HEI coil?

So, from the pictures you can see that I have the capacitor wires cut because I attempted bypassing it and learned that it actually still worked, that the reading was just off some how. That's the problem I am working on now.

The ground strap is under the coil cover; it goes from the corner coil mount screw to the center pin of the 3 pin plug (sometimes, down to the module, or ground it yourself). The coil cover is held down by 2 screws.

It could help filter some "noise" out of the tach signal.

Hey Guys! Figured I'd bring this chat back to life a bit. This time Related more to the T56 I installed in the car, the manual gear for speedometer,
-where to get a new speed cable that will work with the factory gauge.
- where I should get a new Tach because mine still outputs 3x the RPM's the engine is actually spinning and it has a clean wiring from the HEI distributor to the gauge cluster.
- Rebuild or replace factory Oil gauge? When I hooked up a new pressure sending unit to the factory wire it spikes past 60 and stays put. Yes a sending unit, single wire, not a switch.


EVERYTHING ELSE WORKS! Thank you all an immense amount for the time and effort you've put in to helping me get the car together. I have so many chats going on here and threads I don't even know where to post pictures but so far so good and you'd probably enjoy some of the progress. Some of you could even help me further with helpful hints and tips. Thanks again.

I thought all T56s had an electric speed signal?

Yes but from
What I read there is a way to run a manual gear in there for much cheaper! Just checking. And here is a video of the gauges when it’s at cold start.

I wouldn't say "much cheaper"; there was a thread here a while ago that had a box for about $500. An electric speedo is the cheaper route.

Early camaro uses cable drive on the 5speed mounts right to stock cable. Think it’s like 83-85 But one thing you have to slide gear that is in the tail housing of trans that has electric pickup I did it and worked out great!
