I'm trying to rewire my Deutz 6006 and need some advice. The tractor must have gotten shorted out for some reason before I bouight it because most of the wires going to the instrument panel have melted insulation on them. What is the easiest way to go about rewiring it and how do I keep track of all the numerous wires that go to different places on the panel? Just do one wire at a time? Also, the battery cable that goes to the positive post on the battery is grounded to the frame. Does this mean it has a positive ground? Someone told me the tractor is supposed to have a negative groiund. Thanks for any info. you can give me.
