Alright well im not sure if it has a master solenoid or if what im thinking of is the master solenoid, but its connected to the battery and has two fuses on it (circled red and blue in picture). I tested that to see if it works, when supplied power, the solenoid clicks and I tested for continuity to make sure the power connects and it does have continuity. As far as the wire goes, it has only two wires coming out of the key port, a red wire and a brown wire. I tested both for continuity from the connect point all the way back to the battery and there is no breaks in the wire as it does have continuity. Maybe you think it could be a bad CDI box? or ive also been told it could be a bad neutral relay (circled yellow in picture). It has a starter relay and a neutral relay, the starter relay is where the wire from the key bevel goes and the neutral relay is where the wires from the neutral safety switch and from the starter button go. Also, i havent tried turning the key to off position to turn off quad while its running but i do turn it off with the little red kill switch above the starter button that reads “engine: run, off”. when i turn it to off it does turn off the quad.
