On the road with 12v charging problem

Arctic Fox TC

I have 12v to the camper from the trucks charging system but the TC's batteries are not getting charged. TC batteries charge with either shore power or generator but not with the vehicle charging system.

I have verified that I do have power (using test light) to the plug mounted on the camper. I even removed the plug and verified power slightly downstream of the plug.
Then problem is with camper charge wire to battery

Any thoughts?

Where does the power wire go after it enters the camper?


If I don't respond it's not because I'm ungrateful it's more likely that I have no cell service.

Thanks

My old camper.......
from backside of camper plug----Wiring went to a terminal block that had individual fuses for each circuit.....running lights/turn signals/brake lights/battery

Battery charge wire then went directly to POS battery post

(Gen or shore power go thru converter charger)
