This is the easiest repair I have ever done on any of my lawn equipment.

I found this unit by the side of the road. One power input terminal was loose. Inside it was broken. Replacement was to remove the screws, pull out the wire, and cut the wire next to the terminal. I was able to strip the wire and crimp it in the terminal. I then soldered both terminals for a good connection.

Ordered on/off switch. My switch had only one wire terminal. Replacement had two. I ran a wire from one to a screw as a ground. Switch worked fine.
