I just installed an MSD 6AL ignition system in my 1984 Mustang and all is fine except the stock tach no longer functions. The instructions say to connect the green wire from the stock coil to the tach output on the MSD box and that no adapter is neccesary.

When I start the car the tach works for about a second and quits..if I shut it down and restart same thing.

Has anyone had this experience? or know how to correct it?

Thanks
