malueg2 Posted December 22, 2011 Share Posted December 22, 2011 06 Mack vision that loses all marker lights on tractor and trailer.except 3 on the center of the roof. If I turn lights off and wait a couple of min then they'll come back on. Any ideas? Quote Link to comment Share on other sites More sharing options...
malueg2 Posted December 22, 2011 Author Share Posted December 22, 2011 If i turn switch back on then I maybe get a couple of hours, then they go off. Quote Link to comment Share on other sites More sharing options...
jaysm35a2 Posted December 22, 2011 Share Posted December 22, 2011 Bad ground some where? Quote Link to comment Share on other sites More sharing options...
shortstack Posted December 22, 2011 Share Posted December 22, 2011 My first thought is a circuit breaker. Could have a short somewhere or possibly a weak circuit breaker due to age? Have you added any lights to it? Trey Quote Link to comment Share on other sites More sharing options...
malueg2 Posted December 27, 2011 Author Share Posted December 27, 2011 Haven't added any lights, but noticed if i lift the box a couple inches they come back on. When I put it back down they'll go out and Flickr down the road. Flickering is much worse when box is empty. Definitely think It's a bad ground on trailer.
