Thanks, the second pic confirms my conclusion earlier about the FET jack wiring as well.

Well, I know why neither is working, but at the same time I don't want to get in the middle of anything.

If you could compare that relay to the type like HAD used, you would find that the connection points don't line up one for one.

OK . . .is this an easy fix ?[/quote]

Not hard perse', the 22meg resistors need to be reconfigured (staggered at 1&3 and 2 & 4) and all the other wiring moved to different points on that relay board.

Sounds like it's beyond my knowledge.
