While a mile or two above ground today travling across the country, I was struck by a thought. The CJ has a three pronged power cord. All of the other equipment is two pronged. I can well imagine my problem resulting from a slight difference in the potential from the safety grounmd and the negative line seen by the power supply. Tying the two chasis together as you suggest, Aball, sounds promising. Another quick fix to try would be simply to remove the safety ground from by using an adaptor. That's not a long term solution, though.
When I get back from business travel later this week I will try your suggestion.
BTW, know of any good sources for reasonably good but relatively inexpensive oscilloscopes? Something well under $200 would be nice. This is the type of problem that awakens long forgotten electrical engineering studies. I'd love to have had one to use for this problem.
Cheers!
