I am at work but will send you a picture of the mech when I get home. I believe the coil energizes to open the gate. It's a pretty simple gate to install.

Don't know if this will help but is a photo I took when I was doing my restore..

If that's the case then it could be it energizes to close it.........now that I am thinking about it I want to say that when you start a game the gate closes and at the end of the game it opens back up. At work right now but can confirm when I get home.

it is the same exact as globetrotters. game off gate is open. turn game on, gate pulses closed for a second, then gate opens back up in attract mode. start a game, gate closes.

i came across this thread while looking for a solution for a similar problem i ran into. for the life of me i couldnt figure out why the gate i was using in my scratch build Kiss was working the exact opposite as it should. I finally figured out that the coil bracket actually has two sets of screw holes. if you use the lower holes the gate will open when energized. If you loose the top holes the gate energize when closed. hopefully this little bit of knowledge may help someone in the future.

I see you have the original playfield fuse holder. Its probably EoL and you should replace it while your at it.
