Continuing Problems with Cluster Swap

[Shane]

Here's the run down: I have an 89 MJ 4x4 auto. base model. It had the idiot lights and like eveyone else I wanted a tach and gauges. So I did the swap got the sending units for the temp. and other. Speedo works, but tach doesn't. It work for 1-2 miles then stopped. I have unplugged replugged and cleaned. What could the problem beand can it be fixed?

If you need another tach, I have one you can have for shipping plus PayPal fees. However, I've never used it so I can't verify that it works.

I had the same problem recently, tach worked but speedo didn't. Almost all of the screws on the back were loose, tightened them down and my speedo started working.

Remember that the individual gauges are swappable, so if you can find just a replacement tach, you won't need to buy a whole new cluster.
