I've seen a lot of your videos for my motorized kayak project (just completed), but missed this one. Blew up two PWMs until I figured this out. All good now. Thanks for all of your helpful tips!
it is not a matter of brand, they are made to be this way. The plug is "hermaphrodite" designed with a male and female connectors so it can plug into the same type plug (as opposed to two different plug design all male one end and all female on the other that would be required to form a connection) basically produce one plug instead of two. Now, being in origin an automotive connector type you will find that the wire going from battery to connector will need to have the Positive lead covered to avoid accidental contacts with the chassis, thus it is terminated at the female end of the connector (red wire to covered side). On the wire coming from the charger instead it wouldn't matter if the positive is uncovered as the charging unit shouldn't be working unless connected, so the positive wire is terminated at the male side of the plug (red wire to exposed side). Once connection is made the red wire is continuous across the plug. So it doesn't matter the brand, it matters if you get the cabled plug that goes to the battery/load end as opposed to the charger/solar panel end
There's a feed side and a load side for these. If you connect two feed side connectors together it will reverse polarity. Same if you connect to load side connectors.
What would be a remedy for this situation other than sticking to one brand of SAE. If you have any SAE connectors that are opposite from what you are trying to connect, do you just swap the colors? Like connect the black cable to the positive and vice versa?
not a brand thing, the side coming from the source is cabled in one way and the side that uses it is cabled the other way (automotive connector so the positive attached to the battery needs to be covered, the positive coming from the charger can be exposed). In fact an "extension" wire will be terminated in the two different ways. If you look at the extension in the video you can see how the red wire is terminated with a male at one end and a female on the other (note that in the video when indicated them at the waterproof plug he confused the two and then had to turn the plug around) If you swap the wires as you said, always wrap with insulating tape of the right color at both ends of the single wire, that indicates to anyone else that the wires are swapped.

Thanks Michael.
This got me a few years back, too. Good informational video.
Thanks Darren.

Great video!! i actually ran into the same issue recently with my build!
Thanks Kenneth!

How would you properly connect a zamp ready to a different solar system
It's not a brand thing. The tag piece is used to connect to the other end of the plug (the circular one).

There is a SAE polarity reversing adapter you can buy that solves the problem.

What's the max amps for this connector?
I have used this one because it has a 55A rating. www.amazon.com/gp/product/B08M3NW6BZ/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
Good one!
Thanks James!
Ngl I've done that. I knew I've done it so I connected things accordingly but it is annoying
Yep...we are not alone!
I've made this mistake. Once. LOL
It's a hard lesson to learn. lol
@@Aksmaniyak For sure, but I was fortunate enough to notice upon inspection before I powering up!
And btw, thank you for the excellent content you provide!
