New Coach Batteries and still no 12 power

2015 Thor ACE 30.1
I have just installed 2 new 12V Coach batteries and I get no 12V power to RV. Everything works when connected to shore power or when the generator is running. Prior to installing batteries, the generator would not start, now it will start, but will not charge the batteries. The engine alternator will charge the batteries, but not the converter on gen or shore power.
Is there a circuit breaker or fuse between the coach batteries and the converter?

Yes, and it may be very close to the house battery. It may look like this.

The small black lever, on the left, needs to be pushed up inside the housing.

The red button trips it.

Yes I found that part and it is working properly. I have another item just a foot or so past this breaker that I assume is a distribution block and I have power to it. Then the cables disappear under the MH.

Got a converter.........
Check the LARGE fuses on it (30A/40A)....reverse polarity fuses. If blown NO DC from battery.

The next item in line is the battery disconnect solenoid. The switch is near the door but the solenoid can be closer to the fuse box. Mine is hiding under a draw.

If its not working, no battery power.

What does this solenoid look like? When I flip the Use/Store switch near the door, I can hear a click sound come from the engine compartment.

Is there a way to test this? When I have the radio playing and hit the store switch, the radio stops playing and goes black.

Fuses are good and converter appears to be working fine with AC connected, just no power at the terminals on the power panel on the wires coming from the batteries.

What is this item in the pic? Is it some type of Distribution block? Power comes from the circuit breaker nearby.

Check all you AC breakers. If one or more are tripped, try resetting them. If they reclose and you know where your converter is, see if there is 120 AC where it is plugged in. If there is power there, you will probably need to remove the converter and check the output fuses. If the fuses are good, disconnect the output of the converter from the batteries and measure the DC voltage output. It should be 13 +/- .4 volts. If it fails you probably need a new converter. If the output is in limits, the problem is between the converter and your batteries, you will have to trouble shoot this yourself. Good luck and let us know what you find.

Yes it is, one of the medium size wires will head to the disconnect solenoid. Then on to the fuse panel/ breaker/converter box.

Don't worry about any 120 volt breakers or your converter fuses.
The converter is working to power up the 12 volt system when you plug in.

The issue is between the batteries and the fuse panel.

The issue seems to be past the disconnect solenoid, because it cuts the radio on and off, like its working. My Thor does the same thing.

You have checked the fuses in the panel, yes ?
