Check the resistance of that coil. There is a chart online that has the approximate DC resistance of most coils. If it’s close, then it’s something else. If the resistance is low (like 1 ohm or less), then that could be your short. Depending on where you disconnected the wire, it could still be something that’s not the coil, such as another tie point or broken insulation allowing the wire to touch another connection. The problem with a short circuit is that it’s not shown on any schematic. Also remember that a schematic is a logical representation of the connections, not a physical layout. Just because it shows a connection between a switch and a coil doesn’t mean it doesn’t go through a Jones plug or a tie point, etc. Youre making progress with your isolation, so that’s good.

Good luck,
