Quoted from gottlieb_fanatic:

Hey everyone, im slowly restoring and working out some issues on my first pin. It's a gottlieb SMB. I've got the game working perfectly except for an issue with the right flipper. Im not really familiar with how the flipper systems work on these games so bear with me and I'm sorry if this is a rookie question. When I press the right button to activate the right flipper the coil fires normally, but if I press the right button and hold it to keep the flipper up the coil starts humming and getting hot. Both the left and upper flipper don't do this. Can someone point me in the right direction as to where to start looking? Upon visual inspection everything appears normal. No burn marks on the EOS or coil, the mechanical parts of the flipper function normally. Thanks guys.

Quoted from gottlieb_fanatic:

The EOS switch is adjusted right, closed in the down position, open just as the flipper reaches the up position. The only think I could see wrong was whoever messed with it last did some pretty bad soldering on the coil lugs.

Quoted from gottlieb_fanatic:

Alright, I got a new EOS on the way, the majority of the wires on the coil and EOS barely have any strands actually soldered on, the previous owner must not have been good with a soldering iron.
