hello, this is my first camper and i'm new to all this. i believe i likely blew some fuse but i'm not sure. I plugged into to a hookup and all the lights inside the camper turned on, no problem. i noticed i had a bulb out in one of the lights and went to replace it, bam i lose all power. i can hear the converter buzzing when its plugged in so i'm pretty sure that its getting power. is this just a blown fuse? i flipped the circut breaker but no luck. I can't seem to figure out where the fuse box for the trailer is located. I know this is likely a very dumb question but in need of some help! Any ideas for the camper newbie?
