no blinkers with running lights

[theologyman]

ok guys, need some help on this one. I have running lights just fine on the trailer when i turn them on, but no brake lights or blinkers. When i shut the running lights off i get brake lights and a left blinker, but the right blinker flashes on both sides. Any help would be appreciated! Thanks.

Make sure you are getting a good ground on every light.

No question. Bad ground between the tow vehicle and trailer. Most likely a broken ground wire in the harness or plug.

Take a piece of wire (16 or 18ga) strip both ends then temporarily connect one end to the tow vehicle frame/hitch, and the other end to the trailer frame. Make sure the wire is contacting bare not painted metal. Use vise-grips to temporarily make the connections.

Now try your lights and I'll bet you they work just fine.
