Converter to Battery connection

Trying to understand a connection on 1708bh trailer. Red from converter runs to circuit breaker attached to the frame. Black seems to run directly to the frame for ground. From the circuit breaker, red runs to battery and a smaller red runs to another circuit breaker. From this second circuit breaker, a pink/white wire appears to run to the 12v dc fridge. There is also a black wire from battery to the frame for ground. Based on this set up, if connected to shore power, the converter appears to be powering the fridge directly as well as charging the battery. but if no shore power, the battery is sending power back through the red wire to the circuit breaker and on to the second circuit breaker to power the fridge. I know dc goes one way, but seems to reverse direction absent shore power.

The inverter/converter (whatever the term) charges the batteries and runs all the 12v items in the camper while on shore power. I believe all the 12v stuff runs off the batteries all the time but as you have more 12v demand, you can usually hear the converter’s fan rev up due to increased power demand.

Does your fridge a tri-power fridge? 12v/propane/120v ?

I think you are correct. I am a little confused by your description. See my post to the same question in iRV2.

All 12 volt appliances run on battery when shore power is absent.
Converter charges batteries and runs all 12 volt appliances when on shore power.

Some of the information is a little dated, but it is still pretty good
