Hello, my name is XXXXX XXXXX X may be able to help you with your question. Is your 4020 a 12 volt or 24 volt machine?
Ok, give me just a moment and see if I can pull up a 24 volt battery cable diagram.
This diagram is a 24 volt wiring diagram for your tractor. Unfortunatly I don't have any that show the battery cables them self any closer up. The battery cables are very simple for the 24 volt machines.
GENERATOR AND STARTER WIRING™BR>(DIESEL)(TRACTOR SERIAL NO. 065000-090999)
i need the battery cable wiring because it burns up the batteries in about 6 months
Is the diagram that I posted not what you were looking for?
What specific part of the diagram are you in need of?
Just out of curiousity are the batteries simply going dead as if they have a draw or a more serious failure?
the battery cable because I need to replace them . the system burn the batteries up in short order
over a short period of time the tractor becomes harder to start then it fails to start. I can charge the batteries for a time then start it but when tried later won't start
Unfortunatly I don't have any additional diagrams that show the battery cables aside from the one I posted as I don't have a scaner to copy my books diagram for you. One of my fellow experts may have a better diagram so I will opt out of the question so that one of them might be able to help you.
Thank You, XXXXX XXXXX of luck. I will now opt out and pass the question on to another expert.
