Hi my name is Robert.....

You could have blown a fuse or tripped a breaker if this happened after you changed the battery. What I would do is get a 12 volt test light, go to the starting battery and follow the cables, look for a breaker in-line, below is a picture, normally they like to stick them 18" from the battery and can be on the frame or inside a battery control box, below is a picture, most have a small tab that pops out on them when they trip. Follow the cable to the fuse box and check for power with the test light, when checking for power turn the ignition switch ON. Make sure the brake is set and also the unit is in park.

Normally you would have a fuse box outside the RV manufacturer install and one for the chassis that is normally inside up front, on the chevy chassis it is normally in front or to the side of the steering column, on the Fords the like to stick the fuse block under the drivers instrument panel, it will swing up or have a few screws that you have to remove.

A test light will be an easy way to determine where you have power. I might also have the battery load tested to make sure a cell did not get shorted out when you jumped. Also try removing the cables for a few mins and then hook them up and see if you have power.

Hope this gives you some direction, if you have more questions or concerns please feel free to contact me.... Robert
