I am rather amazed that there are no wiring harness details and it is a grand puzzle. I am now compiling one and will make it available as soon as I finish. Before I ask questions, I would like to emphasis that just touching the existing wiring on the tractor, created showers of sparks. This is because insulating tape dies after 5 or 10 years and twisted old wire, is not a way to fix wires. I now understand the fire hazard around tractors and strongly suggest everyone invest in a new harness as the start of fixing a vintage tractor. from what was there before... I came across what is call Starter Safety Switch which is a funny looking thing up on the right side of the instrument hump. If the wires were disconnected (one of the sparkling wires), the starter is disabled. What does this thing do? It must be a switch but what does it switch from... air pressure.... temperature... no idea. There are pictures on Agriline of it. All of the wires that originally went to the Controllor (voltage Regulator) were massed into one great sparkling lump without the Controller. I presume that a dynamo was replaced with an Alternator and the Controller is not necessary? If this is so, I have three terminals on the "Alternator" and perviously only two wires attached. What should be attached? A final question, the key switch has three positions besides for the spring starter. I am presuming these would be off (key can be removed), electric accessories on without engine, Heater on, and Spring for starter. Electrically this means the heater is always on once the starter has started and the engine is running. Is this correct? I though heaters were just for starting, or are you supposed to switch the key back to position 2, accessory position? I would like to get a 100% harness layout chart and have it available so the next person doesn't have to puzzle so much. [Reply]   [No Email]

The "strange one" is pictured here http://www.agrilineproducts.com/retail%20catalogue/ford_4000_catalogue.html 5899 Safety Start Switch. I have one to the left of the hump of the instruments. It doesn't push, doesn't move but is wired into the starter circuit.   [Reply]   [No Email]

I have a wiring diag for it, but going from there to harness is not so easy. I am working on the zone of the harness - particular function. (I am at work so from memory, things like this) Headlight Zone Blue/Red ----> headlight Starter Zone White/Yellow ---> Starter Switched Live Brown ----> Live return to Controller Brown/Green (connector) ---> ???   [Reply]   [No Email]

Many people have been killed by starting a tractor that was in gear and then ran over them. Never start the tractor unless you are in the seat. get the safety switch hooked back up before you hurt someone who is not as careful as you. good luck.. bill   [Reply]   [No Email]

Does it have 3 cylinders or 4? Start there and folks here can help you get more info on the wiring diagrams for your particular tractor. Greg   [Reply]   [No Email]
