Westinghouse ERL triplex.

I have a triplex,#2 genny is out,so down to #1 & #3. As of late in the mornings only these cars will be parked at 1 with car calls and hall calls on them. I simply have been going in the COP and toggling off my MG in each car then its fine for the remainder of the day until the next morning. Coms are in TERRIBLE shape..fyi. I'm new to Westinghouse. I'm looking for direction on what i should be looking for.

tach on end of generator coming up to voltage? This acts as MUTS if I'm not mistaken. Cycling the generator switch just lets it die down and restart. Have you gone to the machine room when this condition exists to see why the doors don't close?

Go to the machine room. See if the gennys are cranked? Apparently your not getting 80 and 80A which is a start command. That will pick 45s and will close the doors. I'd love to see the relays in this controller when this is going on.
