Took apart the control panels, since I couldn’t get either to do anything. The optics were waterlogged. Once I got that dried up, the spinners actually registered something.
Spinners turn rough. Disassembled one and used some petroleum jelly on the moving parts. Smoother. I would have used lithium grease, but I don’t have any.
Fire button on P1 side didn’t work. Crappy connection on the wire fixed it – while it was in my hand. Leaf switches…ah, crappy contacts. Still doesn’t work when installed. Screw it…install it upside down. *shrug* it works, dunno why.
