Howdy all. I’ve posted this problem on another site but not getting the help I need. We have a 2011 Monaco Diplomat 43PD5 about 35k miles. I can’t tell you exactly when headlights quit working because we usually don’t run at night. I was replacing faded headlight assy when I realized neither low or high beams were working. All other lights work- clearance, tail, brake, turn, backup, driving. I can only find one 20 amp fuse labeled headlights and it’s good. I located HL relay-No Power. I finally located smartwheel controller and believe it is working. With headlights on when I press any of the steering wheel buttons I hear a click and the green indicator light turns red then goes back green. This coach has the Sm 211 REV B controller.
