FFFFF I have no idea why that fuse is blowing then. THANK YOU FOR TESTING THAT! Either magnet blows fuse f20 (3a slo). The transistors all test in spec, both magnets have about 5ohm resistance, diodes all functional. The new 3A slow fuses I got looked different than the old ones (instead of coiled wire in the fuse it was a single strand like a fast, but with a lump in the middle). For science I tried putting in a 4A slow in exasperation and everything worked perfectly with no fuse blow so i dont know what's getting over powered just barely enough to immediately blow a 3a but not a 4a, unless the new fuses are indeed wonky... if the original blew on an unlikely fluke.
The bridge for the magnets wouldn't end up shorting "just a little" right? It should either be wide open or not?
