Mark-

Thanks for your offer...I found what the problem was.....a faulty battery. I noticed that it wasn't cranking out 12 volts, so I hooked up the battery charger and although I couldn't drive it, it didn't miss at all. I understand that MSD boxes
must have at least 12 volts otherwise they get real testy. So today, a new battery goes and I anticipate that should resolve the problem. If not, I'll be back on this forum for more help.

Thanks to all for their helpful suggestions.

Ron
