Thanks to all those who responded to my message requesting some input with regards to test equipment for near-field radiated immunity troubleshooting. There were MANY suggestions . . . all good ones too.
Ultimately I used an HP Signal Generator and EMCO near-field probes . . . worked very well . . . simulated the failure within minutes, and fixed the problem within a couple of hours (poor grounding - paint where the drawing said there shouldn't be) . . . .
