Roy Posted September 4, 2009 Report Share Posted September 4, 2009 I'd replace the whole unit, Goran. The socket and connections are probably bad. They're not expensive. Link to comment Share on other sites More sharing options...
bubbles Posted September 4, 2009 Report Share Posted September 4, 2009 Yep Short somewhere, hardly worth looking for it, just replace. Link to comment Share on other sites More sharing options...
Uncle Buck Posted September 4, 2009 Author Report Share Posted September 4, 2009 we're talking about my plug on the vehicle correct? Link to comment Share on other sites More sharing options...
Terry Posted September 4, 2009 Report Share Posted September 4, 2009 no if the short was on the plug on the vehicle it would blow a fuse when the trailer is not hooked up most likely...very small chance but it is a short some where you can spend a heck of a long time finding it but if you think it's left follow the yellow wire and the left light but replacing everything is faster Link to comment Share on other sites More sharing options...
Roy Posted September 4, 2009 Report Share Posted September 4, 2009 Replace the left tail light assembly Goran. Link to comment Share on other sites More sharing options...
moparhawk Posted September 5, 2009 Report Share Posted September 5, 2009 Fought that battle for a long time, could find no nicks in the wires nothing. Finally unhooked my side marker lights, replaced the fuse and bingo no blown fuse ever since. Quick fix but worth a try Link to comment Share on other sites More sharing options...
Greencoachdog Posted September 5, 2009 Report Share Posted September 5, 2009 I'd replace both rear assemblies, like mentioned earlier... they're not that expensive. I't doesn't take that long to do either. I replaced my old ones last year with the new sexy LED's!!! Link to comment Share on other sites More sharing options...
Roy Posted September 5, 2009 Report Share Posted September 5, 2009 Yeah, the Dawg is right. The right assembly is the same age as the left one so it's just a matter of time. Link to comment Share on other sites More sharing options...
bigfish1965 Posted September 5, 2009 Report Share Posted September 5, 2009 Yeah and might as well go the LED route while you are doing it. Link to comment Share on other sites More sharing options...
smally21 Posted September 6, 2009 Report Share Posted September 6, 2009 blowing fuses in my experience is almost always pinched wires. check the wires where they enter and leave the trailer and around the mounting points (screws, rivets) to make sure nothing is pinched or grounding to the frame - this is assuming they did work before. if not you may have wired in a short. leaving your lights plugged in does not blow fuses, not sure where this idea comes from. always quicker to replace than trouble shoot, but could be something simple!

Greencoachdog Posted September 7, 2009 Report Share Posted September 7, 2009 leaving your lights plugged in does not blow fuses, not sure where this idea comes from. That's right!... if you have the proper submersible sealed unit tail lights, you don't have to unplug before launching! I think some folks may "cheap out" and just buy the regular unsealed trailer lights... and that's where the "unplug" comes from! Link to comment Share on other sites More sharing options...
Whitespinnerbait Posted September 7, 2009 Report Share Posted September 7, 2009 . I replaced my old ones last year with the new sexy LED's!!! It should be illegal to sell those cheapy tail lights... Link to comment Share on other sites More sharing options...
Fang Posted September 7, 2009 Report Share Posted September 7, 2009 Goran if you're gonna replace buy LED. Princess auto has deals almost monthly on LED submersibles. Ever since I replaced mine never had any problems. Oh and buy the way I'd say you've got a grounding problem somewhere. They're like needles in haystacks Link to comment Share on other sites More sharing options...

boatman Posted September 9, 2009 Report Share Posted September 9, 2009 Hey Goran, Since its only blowing when the light gets wet it is likely due to a bad seal on the light bezel. The wiring is probably fine. Unplugging the lights is fine, but the problem is that the bezel fills with water and doesn't completely drain before you plug the lights back in. It may not blow immediately. Sometimes, water sits at a level below the blub and doesn't short out the socket until you turn a corner or hit a bump etc. I'd replace both bezels as mentioned. Solder the new connections and use waterproof shrink tubing on the wires. Actually, I'd replace the whole thing from the 4 wire plug on back.

Terry Posted September 9, 2009 Report Share Posted September 9, 2009 where did he say it happens when the light is wet Link to comment Share on other sites More sharing options...
boatman Posted September 9, 2009 Report Share Posted September 9, 2009 Sorry, my mistake. I just re-read the post. It doesn't say it happens when wet just that he unplugs before getting them wet. Ignore some of what I said. Link to comment Share on other sites More sharing options...
