I had the same problem on our 04, chassis batteries did not charge while plugged into shore power. With the help of WRV, I found a missing ground on pin D of the interconnect switch. I wired up a ground and it has worked fine ever since. Will try to add schematics to this post. First is the DC system, second is how the switch is wired and third the connector wiring by function. I see I wasn't successful, they are in the photo section on this forum!!!!

I did catch that and surmised the problem was cut in/out voltage in-compatibility. Oddly, that "Not for use..." statement only appears with that particular distributor and is not asserted by the factory literature, which states it will work "any other DC charging source".

This originally lead me to believe the Echo charger solution was not certain.

My solar controller cut-off is 14.4V. The Echo charger cut-on is 13V. If my 110W solar panel(s) can charge the coach bank over 13V, the Echo charger should cut-on and direct currrent to the chassis bank. This appears to have worked with Milo's coach.

Al, thanks, but the problem I'm trying to solve is not charging with shore power connected, it's charging both banks with solar panels, while stored.

I'm still thinking the Echo charger is the simplest and least expensive solution...

I have a 34' 05 unit with no solar panels at all. Forget that WRV put them on every coach because they did not put them on mine. Possibly it was a big favor, at the beginning of 08 I replaced my 6 coach batteries as I always have whether be boat or motorhome. Have the automatic fill and have never had a problem. I pull it into the garage, plug it in and will leave it for 3- 6 months. I do not turn anything off.
