2013 Express E3500 (RV) the taillights and running light are not working?
I have a 2013 Express E3500 (RV) the taillights and running light are not
working. But all other lights and blinkers work. Blubs are good, fuse is good.
Circuit tester shows that I'm not getting power to the fuse. I checked all the
other fuses, and all are good. Wiring diagram does not help, no indication of
how wires come into the fuse box or from where. Any advice?
