MSD & Pertronix ignitors, Is there any history of problems? Options

[Gatornapper]

It's looking like (diagnosis not really started - just happened tonight) I have had both a Pertronix and Hot-Spark ignitors get killed on my 914 on which I've had MSD since I got it.

Not sure about the Pertronix, but tonight both engine and tach started going haywire, then just suddenly died & lost all ignition at 60mph 3/4 mile from home. Had to tow car back.

Something similar seemed to happen with the Hot-Spark a few weeks ago, only without the tach issue.

I do have a .8ohm resister between the 12v from the ignition switch in front of the ignitor. Running an 050 dizzy and blue Bosche coil.

Is there any history of MSD's killing electronic ignitors?

Rickb45 just put in an MSD and not long afterwards, his Pertronix died too.........

If not, any one have any ideas?

Oh, my alternator runs low, generally 12.2 - 12.8v max with a good VR - have new alternator in my garage to put in ASAP. Pretty sure alternator is not putting out spikes, but really don't know as I do not have a recording oscilloscope...... ;-)
