8mm plug sticking and resulting hack
I just had a warranty replacement on a boulder 100w suitcase that wasn’t working right. My suspicion (not confirmed) was the cord at the 8mm plug. I was never able to separate the plugs with reasonable force and several times had to resort to pulling apart by the cords, I suspect this degraded the wires. Maybe it was the arthritis in my hands but I don’t believe I’m all that disabled in that department. In hindsight I think that the plug on the panel was the sticking issue. I have two extension cords and plugging them together in any configuration doesn’t create the same issue and now I also find the new panel plug much easier to separate. So I think problem solved.
But. In case my hands struggle in cold weather or somehow the problem returns I came up with “handles” for more leverage. I thought this might be useful to someone else. Very simple which is how I like my solutions. Two apposing zip ties on each barrel. Sand down those sharp cut edges!
