Continuity should not be tested with the machine on. Machine off, meter on ohms, measure across fuse.
With machine on, meter on volts, measure from one side of fuse ( red) to ground (black).
One way to find the bad coil: Disconnect the gound side ( non yellow) side of each coil. Connect coils one at a time, re-energize machine till you find the one thats energized.
Alternatively, you can measure each coil to ground, and find it if a transistor is shorted . Machine off, meter on ohms.
