2006 Dynasty, tag axle. The driver side rear light was out. Easy change bulb..right! Nope, no 12 volt to bulb. GOOGLED and an old hit from zmotorsports said his was chafed almost through at pass side top shock mount. Back outside, sure enough the same dummy routed mine so it was cut through.
No way to splice way up there, so cut the harness and rerouted and respliced. The same bundle (small six wires) also contains your marker/tailights, so
you could lose your rear end lights. Also had a 1/4" airline that was in a bind there, rerouted. Bulb was fine..two hours and lots of dirt!!
If there are two coaches routed this way there are probably more, check the pinch point before you have a problem on the road. Top of the forward pass side rear shock mount just where the pass side docking light/marker light harness goes around the shock, rubs on sharp edge of steel shock mount gusset. Really dumb routing!!
Just another day overcoming Monaco engineering...I love this beast.
Thanks Z
