MH wont start on chassis battery. Has 13V
I have a 2008 Country Coach Affinity. It will not start (not even try to crank) on the chassis battery. Everything lights up on the dash OK, it even shows 13V on the voltmeter. Turn the key and not...

Loose dirty corroded connections between chassis battery and combiner
When you hit boost you get the good clean solid connections from the house battery
Key, ignition starter, cables are probably OK
Hi, this sounds like the best theory.. because the starter connections must be ok if it works with boost.
My batteries were all dead in storage.. i replaced the two chassis because i know when they got to 1V they were goners. The deep cycles were only 1 year old and seemed to come back alive ok.
So chassis battery are brand new.. but i did personally connect them... so i will remove the battery connections this morning and put some sandpaper to them and see if that helps.
Where is the combiner or what does it look like? I know every coach is different but any help on finding it is appreciated. Do chassis battery go to this combiner first and then to the "chassis"?
One question-- if i turn the key and check battery voltage, there should be some drop, right? I am going to test that this morning too. If they fall to 11.5V then I guess the batteries are toast. But if they dont even budge.. is that really just a bad battery connection? I ask because the voltmeter on the dash doesnt budge.. so i think it is not even trying to draw power
