Running lights

[Lynn and debbie]

While wiring up the lights for the new tow dolly, noticed the running lights not working on my '93 Gulfstream motorhome. It's a gas unit with the Ford 460, F53 chassis. All the fuses in the fuse block are good. The light switch in the panel is good. I'm going out to check for a bad ground per several forum posts, but I would be surprised if a single ground would effect over a dozen lights. The brake lights and turn signals are fine. Is there a relay or an inline fuse somewhere? any ideas?

You may have a dirty socket for one of the bulbs or the poor ground. Sometimes running lights are in series.

Thank you for the quick reply. I went back at it yesterday after my post to check for the bad ground but no problem there. Started to physically follow the wire from the headlight switch hoping to find a relay, and found the wire dangling behind the dash with a female spade lug on the end. Found a rocker switch missing a wire within range and , viola it works. The rocking switch was my "mystery" switch. Was unable to figure out what it did.
Turns out it turns off the running lights. It's a momentary contact switch, so when pushed all the running lights go out then return when the switch is released. I suppose it's for flashing "thank you's" or "all clear" at people?
Thanks again,

For sure? That would mean off the wall voltage lights. It would also mean when one was out, all were out. As the lights are DOT required (and a safety item) I can't imagine many manufacturers or DOT would accept all lights being out because of a problem with one.

This being our first Motor Home, I'm still learning things. My 96 Pace has this button on the floor like the old (for those of you that remember back that far) Head light dimmer switch. I don't know how long it took me to find out what it was for.
