negative ground

Just sorting through some junk and found an editorial in Antique Power, 1991, about buying a tractor that wouldn't run right no matter what the previous owner tried. Pat Ertl remembered what somebody had told him: Don't do anything to an old tractor until you have the repair manual.
He bought the manual, found that the battery had a positive ground. Sounds like a certain red series we all know and love. Anyway, this might be helpful to some of us, since we would ordinarily expect the ground to be negative.
 

Thats how our '40 H came to us.. with a 6v battery installed as a negative ground (dead battery too)..

Luckily, it came with a manual.. I read positive ground, looked and sure enough.. was installed wrong..

I HIGHLY doubt the substance of that editiorial!
If it wouldn't "run right", there is definitely something more wrong than just a battery polarity.
 
somebody is pulling the sheep over his head! pretty standard procedure that 6 volt is pos. grnd.and dont need a manual for that.
 
I took my B wires, cap off, repainted everything. Put the wires back on- by the book, wouldn't start. Finally found a sketch I made, and the wires went on differently. The mag must of been taken out, and put in differently at some time in the past. Someone on here said 180 degrees. Used the sketch, not the manual, fired right up. So much for the manual lol Steve
