Question about dedicated 220V 30AMP circuit

Hello, I have a Champion C30145 winch that's designed to be mounted on a vehicle and powered by its engine battery. To connect it, you simply connect battery leads from the winch to the vehicle's battery, and you leave the vehicle's engine running while you use the winch so that the battery's recharging. I'd like to convert the winch's power source so that instead of running off a battery it will be plugged into 120V outlet in my outbuilding. This building has a strong overhead beam and I'd like to attach the winch overhead and use it to raise the front of our riding mower up with it, so that we can get at the blades and belt area underneath the mower. I called the company tech support but they had no specific advice for how to do this; only said 'consult with an electrician' and that I'd have to get an aftermarket kit. The specs are -- 1.34 hp motor (DC 12V) intermittent duty cycle MPM 1.2 Max Current 150 amps I'd really appreciate some suggestions for this. Thanks!

I'm going out of my mind trying to figure out a problem with an electrical circuit at my sisters house. Before I call in the ex*****ve electrician I thought I'd see if anyone else has an opinion. There is a 110v circuit on a 15a breaker that runs the following items: garage door opener, garage lights, basement hall lights, one outlet, foyer lights, first floor hall lights, and three outside lights. (house built in 1979) So what happened was three days ago all of the above items stopped working as if they had no power, the issue is that they do have power, however both the hot (black wire) and the neg (white wire) are showing to be powered. I disconnected every light fixture and outlet and switch that I could find and the hot wires to every box is coming through with the dual hot. There are no signs of any burnt switches, fixtures, or outlets. I also disconnected the negative at the breaker box and it does show it has live voltage. There have been no changes to anything in the house, and this is the only circuit effected. I did check other circuits the same way i checked this one to make sure I wasn't looking at something wrong and I did get what I consider a normal result of only power on the hot side. The breaker has not tripped (and is currently off) Any thoughts or ideas on what could have happened or where to even look? Thanks
