I'm having a problem with a couple of switched solenoids on a System 11 game. This is out of my realm of expertise, and trying over at rec.games.pinball didn't get me very far.
The issue is a stuck on flasher when I first power on the game. Then, when entering diagnostic mode, the solenoid across from it in the chart (see picture, circled in red) locks on and the flasher turns off.
All I know from looking at the schematic is that there is a "A" side of solenoids and a "C" side. The game will blow the F2A side fuse after about 30 seconds or so on the Aux power board if that helps any. Any ideas?
Edit: Also, I did try a friends Rottendog MPU in this, and it did not have these problems when that MPU was in. This is an issue with the original MPU.
