The engine alternator charges my house batteries. It stands to reason that the house power could charge the chassis battery, I know it doesn't on mine but I could see how one might think it should.Not like! Charging dissimilar batteries is a no no
Well with no more information all I can say is It should. Best practise would be to test it and see. With it hooked up and the house batterys charged cheack the voltage on the Chassie batterys. They should be around 13.5-14.4 volts. if they are charging. 12.7 volts is full charged.When I hook up to shore power with my Wayfarer, does the engine battery get charged as well as the coach battery?
Thanks,

I almost turned this into a rant, but I tried to stop myself.
You could ask an engineer working in the battery industry for his opinion concerning connecting dissimilar batteries together, but I saved you the trouble.
In my opinion, the fact that how the RV industry acts like a bunch of backwoods shade tree mechanics on this topic, only serves to bring to light the true nature of the industry.
Now I can only tell you how this job should be done, but you have the right to do what you will. My history in electronics, industrial electrician, electric boats, tells me the two systems should not be connected unless temporarily for emergency purposes.
There is a reason I don't copy the industry's slipshaud practices.
It is a great way to build in problems.
Sorry for the rant, I tried not to, really I did.
