Îm not too hot in electricity

If I switch the red wire ( +) that goes to the panel to the batteries , I wont have any 12 V in the RV , Am I wrong ?
If so,what could I do then ?

If you can run your 12v systems even when the converter is not charging - meaning, if your batteries power your 12v system on their own - then your internal 12v system is connected to the batteries by some other pathway besides the converter-to-fusebox pathway. Most RV's are wired this way.

(If the only way you can get 12v service inside your RV is when your converter is actively charging, then this won't be true, and you may need to rewire a bit.)

So, barring weird wiring, you should be okay to wire the converter directly to the batteries. Wiring the converter output to the fuse panel means you're trying to force too many amps back down some smaller fuse-panel-to-battery wires.

Ok Ill remove the red wire from the fuse panel and put it on the battery for a test

Did my homework
Transfered wire directly to battery ( gauge 8 ,16 inches )
Still max of 18 amps …..( no change)

Tried to put more demand ,all lights ,fans et ,,,,still 18 amps max
