no charging voltage
Have a four winds hurricane motorhome. Had to replace my 12V house batteries (two in parallel). I checked the voltage at the cables that attach to the batteries and have 0 volts. I expected about 1...

To be clear, the new house batteries are NOT attached to the system. I am looking for the charging voltage at the terminals that will attach to the batteries.
I have not looked for voltage with the engine running, but I will.
Sounds like the voltage I see at the fuses comes from the motor battery not the converter. I will disconnect that battery and see if there is still voltage at the fuses.
Not sure how to test the solenoid.
If you see 12.3 from chassis battery at the DC house panel, that means you have closed the "isolator and aux/start relay solenoid" (which I believe is a dash button in a MH) so you should also get alternator charging if the engine were on)
IMO turn that off while trying to isolate the problem here why no converter voltage at the house battery.
Now, since the batteries are not connected, the 85a gizmo should not have battery voltage on one side but should have converter voltage on the other side ASSuming the solenoid for that set of batteries is closed. Since it clicked closed ( but the light stayed on?), and there is no voltage downstream at the 85a thing, that means the solenoid is still open even though it clicked.
However that leaves why not converter voltage 13.6 at the DC dist panel instead of 12.3 motor battery voltage
I am using OnaQuest's drawing of his MH set-up
