As many know I had the center of my 318 taken apart enough to change the fuel lines from the tank to the carb. I found one wire in one of the connects was loose so I pushed it in until it was solid with tension against pulling back out (I know that much about connectors). I looked for any more issues I may have cause and saw none so I put the battery tray in and finished the assembly to go for a test ride. But before i left I decided to use compressed air to blow out the inner frame rails and around the front of the engine and whatever I could get under the engine tins. Then I went for a ride. At some point the battery light came on.
I made a copy of the electrical schematic and although I can read them I don't always fully understand why some things are the way they are.
My tractor has all safeties disabled (jumpered), per my wishes. I did those years ago. (I'm one of those weirdo's that believes safety is a personal responsibility -as much as humanly possible anyway-, not a companies, or something to be mandated by the government).
Anyway, all that aside... under the fender pan I found the rear lights common ground and placed it where the pan bolt would hold it, (I don't think that's the issue), other than that I can't see what I moved that might cause the battery light to come on.
Any ideas? Never had a problem before...everything has always worked, including the rear lights.
