After a replacement power supply board is fitted, all the pop bumpers and slingshots stop working. Earlier the left kickers had died too.
Pops and slings dead after fitting a replacement power supply: check its fuse map
Cause: Two missing or blown fuses. A backbox panel fuse (2.5 A slow-blow) feeding the kickers had blown, and on the replacement supply one fuse was left out because it had the same number as the display high-voltage fuse on the original board; on the new board that number is the solenoid fuse.
Checks
- Check every fuse on the backbox panel, not just the boards.
- Read the replacement supply's own fuse chart; do not assume the fuse numbers match the original board.
Fix
- Fit the correct fuses in every position the replacement supply's documentation lists, including the solenoid fuse, and replace the blown panel fuse.
