im pretty sure the ignition switch is just a 4 pole three position switch. I don’t believe your switch is working properly or the solenoid terminal wouldn’t go hot when the IGN2 terminal is shorted to IGN1. I think there’s something wrong with the switch contacts internally. If IGN2 and SOL are shorted together when in off or run then the switch is bad. I’ll post some schematics tomorrow if I can. Happy New Year!!!
