IDK...
I find it very odd to have both circuits messed up.
Hook up Recap.
The big hoop goes to the top post, battery side of the stinger.
Both small loops, go to the small post of the stinger. Doesnt matter which one.
The green wire needs a ground.
The yellow wire needs a key-on source. (Or other 12v to test)
And that's it.
I personally test these. but, I make no claim of perfection. lol
Let me know what we need to do to get you fixed up.
