Thanks, we need to look more into the timers and bases i think. The number 2 car was running on auto and accepting car calls. Hall calls was giving intermittent issues and then all the sudden it just stopped working and now all the relays are chattering while the car sits idle.

At one point, car and hall calls were working. Then stopped. Hit the door one time and then it started working again.

The car controller, we have removed every relay, installed nee pin and tested each relay. We have been trying to check the bases/sockets to ensure they arent too loose.

Moving to the dispatcher next. Any suggestions on the timers?
