My new black hole is blowing the F10 fuse on gameplay then showing an SW06 bumper error.

I did manually move the pop bumpers prior to getting this error and noticed my upper center coil was slightly stiff, but still moveable. I also cleaned all the contacts of the switches after getting the error.

I do not believe any of the pop boards have been modified but I am curious if it is the board needing the upgrade or if I have an issue with a switch or coil.

I swapped the boards, it still blew the F10. I then checked the upper right diode, out of circuit, it tested good. I ohmed the coil and it looks fine. It is an a-1496.

I will check the voltage at the fuse this evening. I have been putting a 2A slow blow in. I don't have any 2.5s. I did end up blowing the F13 fuse when I swapped the boards. I did check for metal possibly shorting and that does not appear to be an issue. I need to pull the pb board, I believe I may have a failed transistor.
