Left turn question

[dewyg]

When i turn my left turn signal on the fourways light up on my trailer and truck. All the other signals are normal except for my left turn which lights up all lights. Any suggestions? When my truck is not connected to the trailer all my signal lights are fine.

Are you sure it is the turn signal lights and not the running lights? If you have a short in your trailer wiring between the left signal and the running lights it might backfeed the truck through the trailer connector. I would think the truck lights would be sort of dim on the right side.

If the right and left turn signals were shorted then I think both right and left would light all the lights.

Check over your trailer carefully for a spot where the wires are pinched. Also take out the left turn bulb on the trailer. The short could be inside the bulb if the filaments are touching.
