They showed nothing, not even an instruction in the box I even contacted qtp directly aswel bit no joy the agent I got it from assures me it's internally regulated I might just try til hook it up and see what happens
Yea I noticed that, I took a chance and wired it up anyway removed old v reg. heavy cable to battery and smaller spade terminal to battery light, fired her up battery light went out and battery Is holding steady at 14v + at idle, seems good to me?
