Hello, I am new to the hobby and to Pinside. I have hit a roadblock on my first pinball and need some direction please. I just got the machine and when I switched it on the replay knocker sticks on. I disconnected the molex and moved on. At this point the solenoid to kick the ball into the shooter lane does not fire. The flippers and everything else seem to work but I also noticed no fuse in the F2a slot on the aux driver board. This is a newer model that is a replacement for the origial but the original had a transistor or something (w8) in place of a fuse. If i put a fuse into the slot, the relay on the aux board sparks and sputters. Also the component at BR1 slot is getting extremely hot while I was testing. Do I have a short somewhere? Any direction on the next step would be appreciated. I tried to trace all the wires and checking all connections. Also the GI relay clicks rather loudly as it switches but this may be normal?
