I am using my Dad's 3020 diesel and the batteries went dead. As I was in the process of hooking the charger up I noticed that the second battery is not hooked up right. The cable from the first battery(+) is hooked up to the (+) on the second one and the (-) goes to the starter. I've never run into this and don't know what to do now. Should I charge it this way or change the terminals around so that they are the way they should be? Will the battery be OK if I change the cables around? He has not had this tractor very long, so I don't know who set it up this way. Advice please...Thanks.

That sounds like a John Deere "floating ground" system. The theory is run the accessories on 12v, crank the engine with 24v.
Don't change anything!!!
Charge each battery individually as it is connected. I would ask dad what he wants to do as there may be a warranty issue if he just bought it. This system appears to be a nightmare to understand, diagnose, or repair. I wouldn't touch anything without a manual to refer to!

Do yourself a favor and get rid of the dead Deere and get an IH or Allis or Oliver or a Case. Anything but a dang John Deere!
