    All of sudden my 2009 T800 will not flash my marker lights. Replaced the relay and check all fuses. The marker light and all of the lights work fine the relay is clicking when you flash but the lights stay on or don't come on during the day when the lights are off. Anyone have this happen??

    Is it happening with the same trailer ? Some one may have jumped the marker light wires in the nose plug ?

    You just have to take your test light and follow it thru, no other way
