My trailer is less than a year old. When I back up, the surge brakes lock. I have reverse lights and voltage all the way to the solenoid. Does this sound like a failed solenoid?

Could be, but in my experience, a failed solenoid is very rare. Fluid level is good?Originally Posted by Sgthagins

Yes sir. Almost to the top.
If you are using a 7 pin plug, and have a 5 pin available on your tow vehicle, there is a work around to quickly determine if a fuse is the problem. In the tongue of the trailer there is usually a 5 pin plug that plugs into a 7 pin adapter whip. Unplug the whip and pull the 5 pin out of the tongue to the tow vehicle. Flip it upside down so the four female ports are on the four male poles on the tow vehicle end. The male pole of the trailer line will be left unused. Turn your lights on the tow vehicle to the on position, not auto. This will send power to the trailer and override the surge brakes. If this works you know you have a fuse issue on the tow vehicle.
Here is another tip I saw from BBC board http://www.bbcboards.net/showthread....=1#post9699931

Ok, thanks KP. I'll give that a ry. I do have the 7 pin and it's attached to a 5 pin in the trailer tongue. I appreciate it!
Failed solenoid or the solenoid has a bad ground. There is generally a screw for a ground wire on the solenoid body.
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
Let us know what you find out....

Weak ground.
