Thanks for the info Rolly. After inspecting incoming to rectifier did find a degrading terminal. That picked up the voltage to 122vdc after fixing. I still only had around 100 DC going to coil. I was able to scrounge up another print somewhat similar, and found, I believe X1A contact 1, 2 not making good connection. Elevator back running. Shortly after had a long talk with customer stating it was time for a MOD. This is the only Otis in the facility. Everything else has been modded in the past 10 years or so. This is the elevator going to the control room on the 5th landing of a power plant. Mentioned it might be wise for operations to forgo a small raise this year in order to have a dependable elevator. Apparently "there is no money for a mod"
I call bullsh** on that!
