I only have 21v on my 50v test point. Swapped boards and it works, so problem is on board. Checked the AC coming in and it's fine. I see that C5 is a component I may want to replace, is there a BR3 on WPC95 boards?

Quoted from PinballManiac40:Technically, it is better if you start a new thread. WPC95 driver boards have 4 separate diodes that essentially make up one bridge rectifier and there are quite a few diodes on the board.
Are you testing the voltage with the coin door closed? What test point are you testing at?

That is why I couldn't find a BR on that board. Coils stopped firing, then fired at reduced strength. Coin door was closed and I tested that switch.
There isn't any 50v on the board at all, it measures 21v throughout the entire line, but the AC looks to be coming in correctly. The board is out of the game now, so I was going to make the repairs.
