Marinco mod cover won't stay closed!

[chrispaine]

I have two vehicles with the marinco plugs on them and they work great. But the covers are loose and in this cold weather won't stay closed very well!
Any ideas on how to keep them closed?

[codysweat]

a dab of super glue untill needed.?

[chrispaine]

No, I use it every day!

Maybe a magnet glued to the inside of the cap and maybe one behind whatever you've got it mounted to? depending on where it's mounted obviously....

Not a bad idea, but I don't see anywhere to put a magnet. Its almost like it needs a lip or something to grab to stay closed but I can't think of an easy way to do it.
Anyone know of a better block heater plug end? I know the big rigs use some good ones.

I haven't had this problem, but I just put mine in a month ago. It looks like you could fit an (properly sized) o-ring on the inside of the lid to create a tighter seal. This might be enough to keep it shut.

A strip of good electrical tape around the inside of the cover? Might make it fit a little tighter...

Either what the above member said, or even a rubber band to make the connection tighter. Mine stays closed fine and it is 8 years old.

Thanks guys, my first truck with this in it was fine and always stayed closed. Now I'm big on not buying junk from over seas when I can and I do remember the first one was made in the states. The latest Marinco plugs said made in Mexico, just like that the quality must have deteriorated! I will have to look for some made in US left overs!

I am having the same problem with mine. The issue never happened until it got cold and the cap now won't stay closed. I think I will try to wrap the lip a little bit with electrical tape to tighten up the fit.
