Over many years I've had a few MSD boxes fail or cause trouble. One thing I would not do is send it back to them.. Waste of time.....sell it or trash it and buy a new one....I have had at least 2 7AL2's fail or cause missing. 1 Digital 6 failed but it may have gotten wet so I don't blame the box for that one....

I work on Inverter type welders and they don't like water either!!! Solid state....very high tech electronics....

The usual Nascar "Cup Car" has 2 seperate MSD's and a switch for the driver to use should he have an ignition problem.....

Mallory supplied the ignition boxes to one of the NASCAR round track series and they used to say they never had a box failure out on the racetrack.

I would use a Mallory in a heartbeat but MSD is what everyone is familiar with and their Digital boxes have features that are very helpfull to some....

I have a freind who just installed a Digital 7 with timing control to help him with a very temper"mental" car.......I am anxious to see if it works for him...
