    Hello and thank you for reading this!

    O.K. my 6volt battery recently went dead so I purchased a new battery and
    installing it I am having some very wierd electrical problems.

    When I turn the key on one position, the gauge lights come on but as soon as
    I move the key to the second position to turn over the motor, all electrical
    functions cut out and stay off for about 2-3 minutes. I have tried jumping
    directly to the stater/silonoid and the same electrical/short problem
    occurs. I have tested the battery to make sure it was fully charged and even
    tried a different battery.

    The only think I can think of is... I was trying to charge the old "dead"
    battery and accidently hooked up my 12 volt charger to the system instead of
    my 6 volt charger. I also tried to start the tractor while the 12volt charge
    was hooked-up to the tractor. Could this have blown something out and if so
    what part would it have broken??

    Thank you in advance for any help or suggestions!!!!

    Hi Jim...

    Suggest taking the battery terminals off again, clean
    and polish them thoroughly with a wire brush or sandpaper
    or a gentle file until they're nice and shiny...

    The theory is that a "poor" connection acts fine while
    you draw little current; but as soon as you try to draw
    a real load with the starter motor the tiny connections
    melt like fuses and open the circuit.

    Hope this helps.

    Take care.

    Start by cleaning the battery terminals. It's possible you damaged a
    voltage regulator somewhere as well.

  4. Ehem, don't get me wrong, but are you sure you connected the batt with
    the correct polarity? Stupid little mistakes like that are often the
    hardest to track down.

    As others have replied, it sounds like a bad connection, either at the
    battery posts or at the other end of the battery cables. I've jumped 6 volt
    tractors with 12 volt vehicles with out problems, there's noth much to
    break in an old tactor. also be aware the the tractor may be a POSITIVE
    ground system.
