When I look at the schematic with the batteries, BIRD, Trombetta and Isolation relays, I don't think putting a trickle charger on the house batteries will "bleed over" to also charge the chassis battery. I do not see how the isolation relays would function to allow charging current to go to either the house batteries or chassis battery. The isolation relays would be set to isolate the chassis battery from the house batteries while the house batteries are charging. When the house batteries are fully charged the isolation relays would have to function to then isolate the house batteries from the chassis battery in order for the chassis battery would then charge. I just do not see how that solution process would occur. The charging current is going to go to one set of batteries or the other -- it is not going to be simultaneously applied to both the house and chassis battery at the same time.

It strikes me that if using a trickle charger you'd need one for the house batteries and another for the chassis battery.

I could be wrong and I know there are many on this forum far more knowledgeable of Thor electric than I am. If I'm wrong about this, I hope they speak up and provide you the best information.

As Ive said on this forum probably a thousand times, "Owning a Thor RV is an adventure in self discovery."
