So I hooked up a wire to one of the 2 wires on the back and it started to work. Charging perfectly. So even though it said it was a one wire, you still need to have at least the voltage sense wire hooked up.
If you have the right alternator it should charge with a single wire going from the big terminal to the battery direct. All other functions are done internally. Senses voltage from the "battery wire" and gets power to turn on the regulator internally as well. Not sure what is wrong but good for you for getting it going.

Worked on the "big rigs" for 45 years now just riding my Wing whenever I can. Gets cold in Wisconsin.
