I know there are a lot of friendly people on this site who will help us all if we need it but I am lazy and I like to give people my lazy man's way of doing things. Anytime I have an electrical device that goes through many safety circuits and relays I say jump it. you can rig up a wire that will fit the PTO connector up in the front and either wire it directly to the battery or put a simple on off switch in line with it and try to see if it will run continuously rigged like that. If it won't then it is in the PTO. If it will then it is in the circuit. It is that simple. Now when you get into the new and modern "Things" where there are tiny circuit boards and diodes and safety computers then being lazy gets hard. The bottom line is that if it runs off of 12 volts and you hook up 12 volts to it and it doesn't run then you know where to start. BTW, the gap is nothing more than a gap between the outer rotating surface and the inner surface. If you take the belt off and can rotate the PTO pulley freely then it is probably ok. If it is so far out that it rotates freely and does not work then it is too far out. I just tightened mine up until it didn't turn freely and then backed it off a little bit at a time until I could spin it freely. Bingo. It's perfect. Good hunting!
