Battery hook-up for "H"

It was originally positive ground. It will work equally well either positive or negative if properly configured
 
its pretty safe to say pos. ground on 6 volt systems was the going thing on all equipment back then.
 
Both of my H's, 1941 and 1951 are still 6v and are positive ground. My M has been converted to 12v and it's negative ground.
 
It is not "safe to say" that almost all 6 volt equipment was positive ground. Hundreds of thousands of Chevrolet cars and trucks were 6 volt negative ground.
 
With electronic ignition, it must stay the way it is!

Those are polarity sensitive. I don't know what would happen if reversed, probably smoke it!

Also be very careful jump starting, polarity and voltage!
 
An H originally had a 6 volt battery and was positive ground. If equiped with a cut out,
the system will work the same if hooked up negative ground. You just have to polarize the
generator after hooking up battery. And your volt meter will read backward unless you
change the wires on that. But there is no point in it. Just leave it positive ground and
remember to hook the battery up that way.
There are negative and positive ground voltage regulators. So if an H is equipped with a
regulator, the regulator wont take any being hooked up backwards on the ground. You will
smoke the regulator.
Getting kind of hard to see H's with an original set up. A lot of cut outs were switched to
regulators. A lot of 12 volt conversions have been done. If any changes have been made to
the tractor, it is important to remain the same as the changes. Unless you completely
convert it to the way that you want it.
