Maybe I'm not seeing something here, and hopefully this is an easy fix. Sure would appreciate some help.<br /><br />I replaced my boat traler lights today, as one had been busted. I didn't run the new wire all the way to the hitch hook-up, because it was still good. On the lights, I grounded them, and spliced brown and green and brown and yellow correctly. <br /><br />Everything on the lights works (flashers, turn signals, brake lights, regular lights) EXCEPT when I try to turn the lights AND hit the brake lights at the same time. Then everything goes off completely. I'm really at a loss here - I scrubbed the grounding areas with a wire brush to make sure I had good contact, but I'm wondering if this is something with the vehicle/trailer combo. I didn't actually hook up the ball hitch to the truck, but I did attach the chains so that the trailer and truck would be grounded together.<br /><br />Anybody got any thoughts on what is happening here? It's really got me scratching my head. Worked on trailers and lights plenty and never seen anything like this. Almost like a current limit switch, but these trailer lights aren't that sophisticated.<br /><br />Any and all help greatly appreciated!!<br />Thanks<br /><br />AP
