Troubleshooting Lighting on Snowmobile Trailer that Doesn't Work

Published 11/09/2016

Question:

I have a 2002 wells cargo fun wagon snowmobile enclosed trailer that I tow with a 2006 Chevy Silverado 2500 hd. The set up Ive had for awhile now. The truck is wired correctly and other trailers work find but when I plug into sled trailer I have nothing. The light on junction box stays red which it usally blinks. Any thought what it can be.

You have the issue isolated to being on the trailer somewhere. What you will need to do is first check that the trailer connector is clean and free of any corrosion as that's the easiest thing to check. Next you will want to check the conditions of the ground wire from that connector to the frame of the trailer. Since all of the lights aren't working it makes me think the main ground that feeds all the lights isn't sufficient.

Aside from that it could be a wiring issue to the assemblies or the individual grounds of the trailer wiring.
