Marker Lights Out
I have a 2009 Winnebago Access and all the marker lights are out. Headlights, brake lights, 4-way hazards, and turn signals are OK. There are chassis fuses on the cab floor above the brake pedal, some...

instead of pulling fuses I like to use a continuity tester across the fuse. Saves pulling them out.
The circuit resistance itself can fool the continuity tester into saying a fuse is good. This is not a recommended or 100% method!
Yes it is. A fuse blows and there is no longer a connection thereby breaking the circuit. Simplest circuit protector there is.
Look at the bigger picture. With the fuse blown the connection is now on the circuit side, and if it has enough resistance in the circuit it will trip the tester!
Huh?
A blown fuse has no continuity between one side and the other, thus, an open circuit and no lights.
