Re: (ET) Need a lot of detalied how info

Roy:

If the tractor doesn't move in the higher speeds, the field weakening
resistors might be broken. Or it could be a stuck relay. If the current 
pegs
but the tractor goes faster that's kind of life. Weakening the field
increases the current draw a lot for more speed.

As for the charger, there are other people better equipped to answer this
one. Bill Gunn has the parts.

Or you could go solar.
