I have a problem with my space station. one of the caps on the two flashers upper right playfield was melted. I got a replacement and a couple of 25 volt LED's (these are spec'd as 1251 bulbs) After swapping them out and turning the machine on, I smelled that smell we never want to smell. I looked and my new bulbs were smoking. I unplugged that connector for the time being. Swapping out some of the 906 flash bulbs in the top of the back box (letters "TA") I found two partly melted twist sockets.
I tested the sockets and found that I had 50 volts continuous at both sets of sockets. Thus burned out bulbs and melted plastic.
Looking up on the solenoid schedule they are both controlled by solenoid 05C. I notice that the 05A side is a 50v circuit although not used. I checked the diodes on the Aux Power bd, all was fine.
I don't have much of a clue on where else to try to track this down and appreciate any help. I got all else fixed up on this long neglected machine, I just have this one nagging issue.
