4020 dies

[chad-sd]

I Have a 4020 side console not sure on year. It is a 12v negative ground diesel powershift, and it is green if that helps. haha The problem I am having is it dies at random times. I found out if I turn the lights on sometimes that will also make it die. When it dies I loose outside lights and dash lights for a minute or so. I got it to act up in the shop today, so I could check some stuff, I have 12 v at the starter solenoid, and the small starter solenoid. Right below the small starter solenoid is a round black circuit breaker and have 12v there also. I do not have any power at the three rectangle circuit breakers in front of the pto lever on the drivers side. I wanted to check the ignition switch but everything started working again. Not sure how power gets there if anybody has ideas or a wiring diagram that would be great. I have a book but it is for older 24v tractors. thanks chad

I figured it out. Found a heavy gauge wire under the hood above the back of the motor, had a bad connection, all is well.

Its a good feeling when you finally find a simple solution to a nagging problem.

I have been having this problem for a month or two, maybe every two or three days it would die, when i go to check it it works fine. Hate to
drive it on the road and die. thanks
