7 pin connector
Hello,
Hopefully this is an easy question. The female part (on my trailer) looks a bit dirty and doesn't seem to be getting a real good connection and the lights kind of flicker. What's the best to clean it up? I was told you can use battery cleaner and a brush? I was then told to use some electrical contact grease. Any ideas?
Thank You
Mike

Yes to all you said. It's called dialectrical grease. Then use some sort of cover when not in use.

I used dielectric grease on my plugs once and never again. The grease collects dirt and sand, especially when you drop the plug on the ground.

Get some electric contact cleaner and spray it into the contact. This stuff works great:
https://www.amazon.com/dp/B000BXOGNI...osi&th=1&psc=1 and sold at most auto supply stores.
Dielectric grease is great on light sockets, etc. but not advisable to use on the 7 pin plug due to dirt/dust exposure.

Thanks for the info. I think I'll pass on the grease now don't need a dirt and grime issue, just need to clean of what looks like oxidation...

I had the same problem. I hooked up the camper to a friend's truck. Turned out to be the receptical on my truck. I bought a new one for $15 and haven't had an issue since. Another fun fact, you can take a 20amp fuse and "jumper" the connection on the trailer plug across the notch when you are hooked up to electricity. It will light up all the lights on the trailer. Easy way to make sure they all work and easy to find your camper at the grounds.

If you have your trailer plugged into electricity, you can take a 20 amp fuse and use it to test all the lights. If you take the female plug of the trailer that plugs into your vehicle, you can use the fuse and jumper 2 of the slots. As you look at the plug, put the raised notch at the 12:00 position. Use the fuse to connect the 2 slots directly under it (11 and 1 o'clock) . All the lights will turn on. If they don't, you have a bad bulb or connection. It's a trick taught to me by a fellow camper. The key is that your trailer has to be plugged in.

I have a plug made to do just that. Turns on all the running lights/tail lights. We plug it in sometimes about dusk if we decide to take a stroll around the campground. We can see the "lights" of home.
I can also plug in some 12v rope lights at the trailer plug if we take a notion.

Great idea to be able to plug in rope lights!

So I made a jumper as described above to test the running lights. It'll make testing a lot easier for sure.
My question is, can this be modified to do the same thing, but for the brake lights? I know they won't blink, but can this method be used to test to make sure the bulbs are okay?

Sure, you don't even need to modify your jumper. Just move the end of the lead connected to the running light circuit to each of the pins for the brake/turn signal. You will have to do each side separately though. So if you number the running light circuit pin as #1 going clockwise connect to pin #2 for the left and then pin #6 for the right side.

You could make a plug to slide the camper connector into while camped to connect a portable solar panel and controller to top up the house battery. There's direct access right there to the campers 12 volt system.

I tried that and nothing happened. I'll play around a bit more. Maybe the connections weren't tight.

That should work. Also, the right side should be pin #5 not #6. #6 is 12V power. Here's a link to a good diagram:

Well, the last 10 or so replies to the OP were clearly in the "hijack mode" but nevertheless a great tip . RE: the replies that directly pertain to the OP's issue, I do use dielectric grease on many occasions where "contact" is sketchy but never considered the dirt and grime collecting ability of the stuff . Makes good sense though! I did recently have to clean some corrosion from my trailer's 7 pin connector to get the clearance lights to work. I generally use a squirt or two of electrical contact cleaner but in this most recent episode, merely scraping some corrosion away with my fingernail did the trick .
