Coach 312 transfer switch contactors - BusNit - 05-27-2025

My contactors are failing but I believe I found replacements. I can’t tell if the coil on these is 12v or 120v. Any insight? I’m camped out at a former neighbors yard in Mesa AZ. No shore power or hookups. The suns heat is on and if this completely fails, I will lose AC since the generator won’t pass power to the circuits. Does anyone know of the coils are 120v for this era? I haven’t seen one in 12v coil configuration which is why I ask and I do not have a voltmeter on board from the move.

Should be 120 the coils normally have the voltage on them, If it does fail ,just join the wires from the generator to the wire going to the panel and you will be good till you can fix it

Thanks John. I thought of that but I didn’t want to do any work on this until I got it to my place. I did see the coil info and it is 120v.
