Quoted from osudrummer:Thanks all for your comments, yes I have been proceeding according to pin repair. Pulled all fuses and checked for continuity. Will give another look at the H relay and switches mentioned and reseat the jones plugs.
It's frustrating but exciting!
Thank you!!
In addition to checking the fuse itself, check continuity/power on the wires connecting to the fuse blocks once the fuse it back in. I have a 1972 EM machine that was acting funky and it turned out to be that even though the fuse snapped in, it was somehow open, and I had to replace the fuse holder.. strange..
