pic of the regulator
looking at the wires:
red top left is battery power
black bottom left is ground
top right is trigger. I use a switch. HOW DO ZYOU WANT THEM TO COME ON: put that wire in this location.
the rest......top is power and lower is ground for all your rings. in my pic I have 4 rings wired in.
the little screw at the very top on the blue thing......that the adjuster.
your rings came with a max voltage on the bag, set they regulator to NOT exceed that.
you'll need to find the proper voltage using a multi-meter on the terminals and turning the screw.
