ICC Running Lights not working
The ICC running lights on my 2002 Fleetwood Discovery quite working. Fuses are good. ICC rocker switch on left side of dash okay. Any suggestions? Thanks.

If your coach is on a Freightliner chassis , the wiring probably goes through a " Marker Light Relay " that will have to be tested too.

Skip426...Have checked all fuses that concern marker lights, clearance lights and icc lights for continuity and 12 volt power to each fuse. Aslo, ck the flasher switch for the marker light and is working properly. Also, the Marker Lamp Relay is good. Any suggestions? Thanks.

If all the 12 volt circuits are good, you might start look for fault with the ground to those lights.

There is one ground for the front and one ground for the rear. If the front or rear is out, it is probably the ground. If both are out, It is probably a power problem.

I had similar problem with our 2004 excursion. Had almost complete outage, headlights hi & low, fog lights all except turn signals. Like you check all the fuses and connections they all were fine. I traced the wires from headlight to what it looked like maybe a 3x6 distribution board (this is best I can discribe it) on driver side on it I notices couple of white buttons, I pressed them both lights on problem solved. All by accident I discovered the reset buttons, no one at RV service center had any idea about the reset buttons. I am sure this saved me a few dollars. BTW excursion is deisel push front access to headlights wiring. Hope this help, good luck

The running light issue was resolved by replacing a "relay" which was not shown on any Fleetwood or Freightliner electrical schematic. It was in a bundel on the driver's side floorboard. captken1

Sounds like you found a couple resettable circuit breakers to me.
