Would that be f22 or f 13?
You are getting hung up on that linked Schematic. You stated you replaced the fuses. Did you LOOK and check if they were bad? There is a 12 to 14 gauge GREEN wire that GROUNDS the step to the chassis frame. Have you checked THAT for secure connection and ground. What I do and have ALWAYS done, is, I use a 12 volt test light and check EVERY fuse I can find for the chassis with the Key ON. You can do this in less than 10 minutes no matter what Brand or Model Motorhome. From your description I will bet you do NOT have the test light on a GOOD ground for the alligator clip when testing the Step 4 wire plug. Doug
