What I do when confronted with a possible blown fuse is this. I use a standard 12 volt test light. I go to EVERY fuse block I can find on the RVl. With Ignition ON, I probe EVERY fuse. 9 times out of 10, that finds the blown fuse/s and I replace and that fixes the problem. The 10th time will be a wiring failure. After 43 years I NEVER trust the labeling on a RV fuse block schematic. I verify myself which fuses are good or bad. Also, this takes less than 15 to 20 minutes at most. Saves a LOT of time. Doug
