200 amp cont relay solenoid
The battery disconnect button when you come into the bus works a 200 amp continuous duty solenoid that connects the house batteries to the coach. Craig and I both have Royales and his failed, I’m sure the contactors failed, He has low power, we both looked up the part it is a Eaton part and it is a aviation part that is $250 bucks wow, I know cheap relays can get hot, so middle of the road is the Big Boy RV 200 amp continuous duty relay under $70 bucks any thoughts? Here is some pictures. He jumped it for now and back in action.

I think the White Rodgers relays are very common. I wouldn’t hesitate to make that swap.

If in doubt buy two, have one as a spare and if the first one pukes you can use it until you get one that works. Still cheaper that way.

What is on that circuit? Why is it 200 amps? Is this a “jump start” solenoid/relay? If so It needs to be heavy duty I guess. I don’t let my chassis and/or house batteries get low. But anything can happen I guess.Ceiling lights are about the only thing that are on that circuit in my 12v Liberty. It’s one of first things I replace as preventative mx when I buy a MH. Every MH I’ve ever had had a switch near the cabin door that activated a solenoid/relay for the interior lights. It fails with use. The longer and more current/amps/heat it receives, the sooner they fail.
Any brand will get hot. It just depends how much & long current/amps is passing thru it. I’ve installed LED bulbs in all my ceiling lights, so not much current passes thru it now, so it doesn’t get as hot, and it last longer. You could even install a lower amp rated unit in such a case.
12v ??? amp continuous duty solenoids/relays are plentiful on amazon & ebay. Take your pick.
Over the yrs, I’ve heard of owners that have “jumpered it with a wire and alligator clips”, instead of dealing with this solenoid/relay. -
i would just make sure that it is continuous duty. they will all get a little warm. . I literally relaced the tivoli lights solenoid last week that just failed. but yes. these fail often so I would have several onboard. Also 24v versions as those are used for OTR air and a few bus related items.

Replacing relays handling loads like the Tivoli relay in the Liberty A-B system is a common issue and can be corrected by using the small A-B relay to trigger a larger capacity cube relay that handles the actual load.
I have had that Tivoli load get the little green relay so hot it melted the case.

I haven’t had a relay problem, but understand that there are heavy duty 12v 200 amp relays designed for electric forklift use that are good for replacement and hold up very well.
