Solar Panel for Chassis Batteries

This post refers to, and is a follow up to, a previous post with the same title, Solar Panel for Chassis Batteries.

Old Forester, did you ever figure out how the Chassis Battery Solar Charger was hooked up and if there was an isolator in the circuit?

On our 2005 34 FDDS, without removing the fuse block which as a 10A fuse for "Solar" I can't tell how the Solar Panel is regulated or isolated between the House and Chassis batteries. I suspect there's no regulation, but I would hope there was an isolator between the House and Chassis batteries. There are no isolators on the ceiling of the battery compartment or visible anywhere, just small gauge wires running to the connections for the batteries on the back wall of the compartment.

Anybody figured this out?

Thanks,

I haven't figured out how the chassis battery solar panel is hooked up yet, but I haven't seen a regulator for it; only for the big solar panel for the house batteries. It appears to look like a direct hookup to the batteries, unless there's a regulator I haven't found.

As it turned out, my 10 Watt Solar Charger had been "toasted". I finally found what appears to be a one for one replacement, a Go-Power 10W Solar Panel which has a built-in Regulator. This answers the regulator issue but still leaves the battery isolation issue open.

Here is a guess- 04+ coaches w/Vansco & #19 LED to activate the intertie solenoid isolates the battery banks, earlier model years have an actual battery isolator.
The 10W panel produces about 3/4 amp to trickle charge the chassis batteries. In full sun w/max wattage from that panel, if the batteries were intertied I don't think the minimal charge wattage could affect anything.
