OK so I bought my first EM project, Williams Travel Time, and I'm having a learning experience. I was always curious about EM's, but it looked like way too many contact switches and relays. Totally different ball game to what I normally work on, but I figured if I soldered enough wires back together I could get it running again.
Swapped out a fried solenoid and had success with the score reels, but the ball kick out doesn't work yet and the outhole relay constantly clicks as well as the score motor runs, until I manually push the ball off the switch into the shooter lane. A couple random times the ball kicked out and the flippers worked, but didn't last long.
These things don't have DMD diagnostics and I am still trying to understand how it functions electrically as well as all the steppers and mechanical devices.
On my coin door, the only coin switch has 3 contacts with one wire still attached and there are still 3 other wires not attached. I am hoping someone has one of these Travel Time pins and could share the proper wire connections. I would love to see the old girl run proper again.
