We've been taking care of this dinosaur for about a decade now and are a little stumped. Car has been shut down for a few days now at the main floor (2nd landing). All fuses are good. The car will hold calls, but won't leave the floor. Relays 29 (safety circuit), and the two door relays (40 something. I forget which two) are both energized. If I switch to machine room inspection and hold 306 relay (top floor call) it will pull in the up direction relays, but car won't move. If I push in the main "1" contactor the car will travel up which rules out motor, main power, phase relays, etc. Peele door controller. We did find a melted resistor on both of the 72TC relays (see pics) and think this could be related to our issue considering it looks like a set of contacts off 72T control the 1 relay. We're troubleshooting with a set of Westinghouse motor generator prints, but this unit does not have an MG set. Wondering if anyone potentially has a better set of prints? Think i'm on the right track or any ideas? I'll definitely update when we figure it out! Burnt 72TC relay. Zoom inPic of ControllerController Tag

There isn't a potential on this controller, but a 1 and 2 relay for up and down. I went back to this elevator yesterday and made it worse than it was before lol. I can't latch calls and it's 10 inches below the bottom floor. I didn't have time to try and figure out how to get it off the bottom final. Any idea the easiest way to get off the final? Following the wiring on the back of the controller is basically impossible.
Before I sent the car into the pit I could run the car up and down by pressing in either the number 1 or 2 relay. After releasing the down contactor one time, the car stopped, but then acted like it was trying to answer a floor call above it by going back up and then going into leveling on its own. It only did this one time though.
Another note of importance, the synchronous selector isn't moving in the controller. I don't see it listed anywhere on my set of prints.

We're going back Monday. It's a two speed machine. I'm not sure if all the 60 relays are in, but I think 60 is at least. Great tip on opening the brake and turning the shaft to bring it off final. Haven't had to do that in years i forgot about that trick. We are getting 81U or 81D to pull in depending on the direction of the call latched. I've heard the "monkey on a stick term," but not exactly sure what it looks like. There is a motor on top of a shaft that I can spin and the selector will go up or down and make/brake all sorts of sets of contacts as it moves. It is not moving when I run the car off the contactors though which might be my problem. I don't remember a T69, but i'll check. I definitely had the car in between floors, with calls latched and it not going anywhere which, I believe, isolates the retiring cam from being an issue like you said. I'll update monday after we play around with it again!
