Tic Toc Tach and MSD 6A ignition
« on: October 16, 2006, 05:21:14 PM »
I have installed a repro TIC TOC TACH in my 1968 350 coupe.  I have an MSD 6A ignition system.  I cannot get the tack to work.  We have tried every trick in the book.

Any advice?

I may be wrong but with the MSD6A you may need to install the in-line filter from the ignition. Not long ago I tried one of those replacement modules from MSD for my standard HEI and in the kit was a little wire that was supposed to be attached in between the tach and the distributor. Just a though and an idea.................

I would call MSD. Their tech dept is very helpful. We installed a 6A on my son's 67 with a repo factory tach, hooked it up to the tach output on the box and it works fine.
Hope this helps Pat
