have you checked the interlock switches? in addition some ultimate 65s have a fuse in the interlock switch circuit.
you might try jumping them all out as a test
if your around pittsburgh I will take a look for free.
I assume you know there have been 5 or 6 revisions to the 65s main board, depending on the revision status of your unit some require a rewire kit.
Its sad ultimate 65 main boards are so expensive, in fact all the parts cost a fortune:(
