[Farmall] Polarity Change Directions for Dummies

Thu May 25 10:28:27 PDT 2006

Harry,
    The old 6 volt systems were positive ground.  Just connect the battery with the positive terminal to ground.  Then to polarize the system, take a jumper wire and momentarily touch it to the Batt. and Gen terminals on the voltage regulator.  You should see a slight spark when you do this.  This will polarize the generator to charge correctly.
    If the system has been wired and used negative ground, you may have to swap the leads on the ammeter so it will show charge when charging is occurring.  You can verify ammeter wiring by watching the needle when you pull the switch on or turn the lights on.  The needle should deflect slightly to the negative side when you pull the switch.

  Hi all yiu old iron folks out there. I bought an "H" (1950) about 5 or 6 years ago and I have been puttsying with it for that long in my garage. Time makes changes and so does life. 
  I've done considerable work on it but not as much as I would have liked. The generator and the starter have been cleaned and tested, the radiator the same. I cleaned the oil sump and the oil pan and replaced all gaskets.  I rebuilt the carburetor and replaced the sediment bulb. I've replaced the oil filter and the oil pressure guage as well as the temp indicator. There is still much work to be done but I'm forced to move it outside. Now, we have come to , for me, a major stumbling block. I need some direction for dummies on how to change the polarity of the system. It is still 6 volt and system calls for change polarity before using  it.

  HELP                                               Harry Bryant, Downingtown,PA
