Hello, I bought a 4020 at auction this spring and am trying to fix it up before it starts snowing this winter. I'm currently replacing the front axle, working on the loader, and trying to repair the lights. That's where I've hit a snag. The tractor is a synchro range with serial number 135,727. It has already been converted to a 12 volt system. The lights wiring was completly shredded from the six pin harness to all 5 lights. I have that replaced. I can get the rear tail light, flood light to work. I have the bright inner lights working. I cannot get the outside fender floods working though. The six pin harness only has 5 wires going in. Ive used 3 of the slots for the rear tailight, rear flood, and inside fender lights. I think the next two wires in that connector should run the outside floods and flashers. I'm not going to install flashers. Those wires will show 12 volts until I hook the lights up to them. I've made a jumper wire going straight from that connector to the light bulb. I have my ohm meter in series with it. As soon as I touch the wire to the bulb I loose the 12 volts. Take it off, get 12 volts back. I'm also trying to get my dash light to work. It acts very similar to the above problem. Any suggestions or ideas would be appreciated. Is the light switch bad? How to check it? Was the 24 volt transition not finished, etc?

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
