7pin trailer plug power loss

Does anyone know where the fuse for the trailer plug is located. I have found the chassis box under the front driver side. The 30a trailer brake fuse was the only ref I found fuse was good. No power at the rear connector.

Welcome to iRV2
Make, Model, and year would be very helpful! You can add them to you signature.
On my 04 Itasca Horizon, the fuses are in the last compartment on the drivers side. Remove screws and lift the ventilated panel to gain access. You might try turning on the turn signals, and walking around the coach and listen for them.

A little nameplate information would certainly help us help you.
However, if it is the power connection from your vehicle to the trailer battery you are asking about, the 30A fuse is located in the vehicle fuse panel.
I just helped a friend locate a burned out fuse on his Dodge 1500 which was under the hood in the fuse block. He had the battery for the trailer removed and went to hook it up with the trailer plugged into the truck, put the terminals on backwards and blew the fuse.
They are pricey little Devils I might add.

On a lot of RV's, the ignition has to be on for that plug to have power.

I think you should double the grounds. #1 cause of loss of power.
