I'm a little fuzzy after a few beers, but did I read correct that the F9 fuse does not blow when the fuses are taken out for the magnets?
If so, suspect the transistors on the magnet PCB to be faulty. These things cop a hammering and are common to short.
Correct!
The magnet PCB also had multiple dry joints...Do you know what the readings for the transisters should be & also whether black on metal lug or red!
