I was wiring up some work lights from the factory connection and now I have no power at the connection. I tried to follow the electrical schematic but...I'm guessing it's in chinese or another foreign language because it makes no sense to me at all. I have 3 fuses under the hood and they appear fine. Are there more I'm missing? What I did was to plug into the hot connection and put it through a toggle so I could turn it off and on when I needed it. It worked on paper...Any ideas or suggestions would be appreciated

Do you now not have power at the connector? Trace the wire back? If power at conn but no light, is ground consistently good at the light? ROPS not always good at integral ground.

did you use an actual meter to test fuses?? check for continuity.

The light I'm trying to connect is a single wire work light so it grounds through the bracket. How would you ground a light that grounds through he mounting bracket? I used a test light on the fuses and it lit on both sides plus all the other lights are working.

err, as long as the bracket is mounted on metal fender, the ground should be fine. On my old JD870 i ended up having to scrape some paint off around where the nut touched the fender to make the ground contact work. As long as the fender isnt plastic it should continue the ground. Unless the fender is isolated from the ground by rubber washers.

Thank for the help. So now I have the light working and here's what I found. I had power from the connection out to the toggle and then out to the light. The problem wasn't the ground...I didn't clean the wire off good enough from the light I was trying to connect. I thought I had it stripped but there was two layers of sheath on the it. Geez...guess what happens when you completely strip the wire...power. The light works. This is why I'm not an electrician.
