Neighbor reported ball wasn’t appearing. Checking, no solenoid worked, including flippers. Only common element was fuse F12, which was blown. Replaced with 5A SB. Solenoids started working.

Doing a full solenoid test, magnets for The Power did not work. Tracing with a meter led to a 5A SB fuse under the table by the “Hi-Powered PCB board”.

Replaced fuse with 3A SB breaker. Only the left magnet tripped the breaker. Disconnected left magnet. Breaker still trips, so problem is upstream.

Pulled the board and D1 is shorted. Replaced a 1n4007 with 1n4001. All Power magnets worked without tripping the breaker. Replaced fuse and returned to service.
