Tachometer on a 1970 Cuda with rally dash

[1970CUDAAAR]

My tach does not work - yes I have another tach. I would like the one in the car to work. I bought the following part from Year One:

Tachometer harness, Engine-side for 1970 E-body big-block models. Reproduction

do you think it will help? Any other suggtestions on how to fix the problem. Can this tach be refurbish?

Yes, it can be refurbished. Redline Gauge works or others could do this work for you. Redline Gauge Works

In mine, the circuit board was fried, so I repaired it with this tach repair kit- RTE 67-74 Tach kit - rte

Do you have the tach hooked up to the negative side of the coil? Gray or white wire iirc.

I have replaced the guts in two tachs with the RTE kit, it’s an easy job and comes with good directions; and they are much more accurate than a factory tach.

Redline Gauge works takes a loooong time and will cost you much much more the the RTE kit.

I did mine with RTE too. They used to sell clock kits too. Did that as well.
