This afternoon my wife said....

"I noticed the
tail lights of the trailer on this morning.
 It's not hooked to the truck.  Are they supposed to be on?"

When I went out to look and sure enough the rear tail lights were on.

 

I went immediately to look first at the "emergency brake" switch and then at the front 7 pin connector...which has a "rubber cover" on it to keep water out.

 

We had 2" of rain in the past day and that rubber 7pin cover did a much better job of keeping the water in.

I drained the connector, blew it out and dried it with air.  Then cleaned it and lubricated it with electrical silicone grease.

 

The lights are no longer on.

 

I'm assuming this was a draw from the house batteries through that connector.

 

Passing along if of any use to folks in the future.

 

If there's a similar post somewhere I didn't find it in a quick search.

It’s been talked about before, but it’s good to have it brought up again for people who haven’t experienced it. It is odd to go out and see your trailer lights mysteriously glowing.

 

If it’s any consolation, Airstream owners consider this a ‘feature’ and they’ll even purposefully short out the plug to keep their exterior lights on.

You can clean and dry the inside of the connector and the wire attach points with alcohol and a soft brush (or use spray contact cleaner). Then seal up the cables where they enter the back of the cover with silicone sealer. If you keep the plug dangling down when not in use, it will stay relatively dry inside.

John,

 

Thanks for the tips...I'll clean and seal it later today.

I'll also be using a couple zip ties to make a simple holder on the tongue under the "basket" so I can stow the plug our of the rain.

For the last 50 years I have just let my trailer plugs hang down, I also try to store it somewhere under the trailer tongue where it is somewhat protected from rain, etc. I give it a shot of electronic grease every year or so, always works for me. I was thinking of purchasing a plug cover, but then thought why, 50 years and no problems.

I've done a modification to add an Optronics 7-Way trailer harness plug protector.

 

Here's the link to the part I used from e-trailer.(Including shipping and tax < $10

And here's where I mounted it...on the back of my Tongue Box.

I used stainless #10 bolts to mount the unit.

It could be mounted with zip ties to the bottom of the tongue as well if you don't want to drill holes.

The cover is a semi rigid type of rubber material but with enough flex to make it easy to insert or remove with one hand.

 

In any case, I switched to this after my original "rubber cover" leaked.

Hi, John, 

Does this mean you take the connector apart?  We started having this problem recently, I cleaned the contacts with alcohol and applied dielectric grease, to no avail.  We still have the phantom taillights, so I thought the moisture must have gotten inside.  We always keep the plug dangling down, so I am unsure why all of a sudden we're having this issue.

If you keep the plug dangling down but didn’t seal the cable where it enters the back of the plug as John mentioned, then water can still get in there.

don't know if this is relevant or not, but i've noticed that if i hit the door lock button on the door handle of my pickup, the rear lights on the Ollie flicker. but if I lock the truck with the key fob, it doesn't do that. my trick is a GMC, yours is a Chevy, so, maybe?

I'd say you may have a moisture problem somewhere,  also. Possibly. 

In Liana's case,,her connector may be shot. Some work with a multimeter can give a better picture.
