I have some missing prints that I need for troubleshooting this jewel. Since doing 5 year tests this week one of my units run on inspection in the up direction. Acts like it is still at the bottom, butirection is made up. The tool would indicated it is lost and under normal conditions it should run to a terminal to find itself. It would see a signal to run down, but never would pick the brake. It would only pick brake in up direction. It is now in the overhead after been run up so many times on inspection. The relays that I know I need to pick the brake are PR and PPP. I am not getting them to pick. Any help out there.
