anderson plug - too stiff to plug in and out...

Agree and when you get the chance give it a good strong hose out. Don't lubricate as the lubrication will gather dust and much and make things worse.

Here is a good view of what they look like and how they go together

Pull them apart and have a good look......both contacts should be the same on both plugs.....possible one contact has slipped back a bit off the spring loaded clip ..

I've never had anderson plugs too hard to push in...in fact the opposite !!

They needed to be straightened! They had a slight bend, couldn't tell before we pulled it apart! Thanks for all the responses, all sorted out now :) cheers!

Agree, Silicon Spray is the way to go. It does not collect the dirt and dust and is cheap to buy @ Cheap as Chips. Put a can in the vehicle as it has many uses.

Yep, and that goes for any other lubricant....an anderson plug needs nothing.....if full of dust or mud, hose it out and let dry..

If you want to make sure it has clean contacts, push them together and pull them apart a few times ( 10 times if it takes your fancy )..

Don't file the contacts either....if the contacts look "dirty" or damaged, unsolder and replace them.....they are cheap as..
