Reply to "Tach don't work"

It, the MSD, won't run the tach with a system using the Ford distributor. I am not a novice on that particular set up.

The DT tach is not a Ford Tach. It does work like it though in that it runs in series with the coil.

With the MSD, the blue tach wire in the harness is dead.

The MSD tach adapter will not work with the Ford distributor.

The simplest fix is to change to the MSD distributor.

I went another route. I kept the Ford electronic distributor for reliability reasons.

I replaced the Ford electronics brain with the Pantera Electronics brain.

It has several advantages to it. It works with the stock tach, it retards the ignition 14 degrees at starting to turn the engine over easier, it plugs in, it plug in to a high voltage coil, has an adjustable rpm limiter, has led system lights for checking operation at a glance.

No one, I repeat, no one was able to make my tach run with the MSD 6a irregardless of what MSD add ons we put in the system.

No matter. It's fixed and is staying this way.
