Park Power Connection

My Wildwood TT has a 30A Marinco removable power/cable system. Ever since it was new, the ring on the male cable connector that plugs into the trailer has had trouble grasping enough threads to tighten the plug securely into the trailer. The ring only has about 1/4 inch or so of threads available to tighten up on the trailer fitting. Although it won't tighten the plug in, it will grab enough to keep it from falling out. My problem is that (1) I am afraid one of these days the connection will start arcing as it is not really tight in the trailer fitting or (2) being that it is directly below the city water connection point, a small leak will develop and get into the plug causing a short. I know the female connector / threads on the trailer are good as when in storage, I connect a Marinco 30a to 15a adapter to the trailer for power from an shop 15a outlet. This adapter tightens in securely as I believer the 30a on the power cable should. Short of buying a new Marinco cable, does anyone know of a fix for the cable plug (new tightening ring) or have another idea..

You could try swapping the ring from the 30 x 15 adapter to see if that works on the Marinco cord.

If I remember correctly, the Marinco should be twisted clockwise after being inserted. That effectively locks the plug into the connector, preventing it from coming out until it is rotated counterclockwise.

I have the same plug on my RV. My plug, you have to push in and then twist plug and then screw in black ring. Check to make sure all the screws holding the plug box are screwed in all the way. My ring is up against the screws when tightened.

X2 on the same set-up plug into trl and then twist clockwise to lock, I then can twist the black plastic locking nut 4-5 turns to secure the plug.

My dad has that same setup. On his motorhome its easier to pull back the rubber boot and plug in. Remember that plug is the same as any other twistlock polg in that it needs to be inserted and then tisted to lock. Once its locked you can slide the boot over it and tighten the ring.

Worst case you can buy a new end. While expensive, if you are handy, you can change it out.

I had the same trouble--------------

I had the same trouble with the ring not being able to tighten. Forest River replaced the whole power cable under warranty. The replacement cable was black and 5' shorter.

I was able to remove the over sized ring from the original yellow cable, purchased a yellow cover and ring from camping world. The yellow cover was very easy to remove from the black ring from Camping World. With some elbow grease, screw driver blade, I was able to remove the ring from the orignal yellow cable, replaced it with the ring from camping world. It now fits tight onto the fitting on my RV>

Good luck

Same thing as boats - try to use BOTH hands when tightening the sealing ring. For some reason, known only to engineers with whom the developers are friendly, using both hands will allow you to maintain alignment and keep the ring even when getting it started. Try it one day, you'll be surprised.
