The cannon (gun) motors and flipper stop working together, and some test points on the power driver board show no voltage.
Cannons and a flipper lose power at once: a fuse that looked fine was blown
Cause: A blown fuse on the power driver board, which looked intact by eye.
Checks
- Pull each fuse in the upper right of the power driver board and check it with a meter on continuity, not by looking.
- Check the test points again once the fuse is replaced.
Fix
- Replace the open fuse with the correct value and type; if it blows again, look for a shorted coil or driver.
