IIRC, “crowbar” of the power supply is what it was called. I’d bump the 5V to 5.2 or 3. Those are some old 1210’s or 1200’s. I’m not quite sure what you’re saying about “…not AC, 5 at 5.2…” Catching it failed, drop the Dispatcher 5V PS to about 4.6, then back up to 5.2 or 3. Or, once reset, bump it to 5.2. Continued failures could be the PS itself. In your picture, Car 1 is offline. Any reason? You’ve got the PCD and manual for those units? Oh- you probably know, but everything do do with those US cars is a capital O as in obsolete. CCU/COU failure…good luck.

Check that personally jumpers match the MJ jumper. You open the MJ jumper ( normally red) and see how the jumper wires are configured and make sure they match the elevator assignment of the personality board. Can can switch #1 car assignment on personally board but you must also match with proper MJ jumper. Otherwise check jumpers with PCD to assure they match actual physical locations. If you shut down #1 car then power for calls will be supplied by #2 car and so on. So if you have a bad board in the string you can find it by shutting down cars one at a time till problem goes away. If your modding a car the daisy chain has to be maintained and personally compensated. Sorry these are 1200s check PM

I haven’t heard from you I guess it’s fixed? I’d be surprised if it were. Those 1200’s or 1210’s were a beast even for those with an ounce of U.S. knowledge. But they sure beat the old MDU relay control! Ha! Them were the days.
