[Farmall] FARMALL H BATTERY DISCONNECT

[Darrell Ratliff]

Richard – 6 volt systems were normally positive ground.  Put your disconnect switch in the hot line (negative in this case).  It would work in either line but it is common to put the disconnect in the hot line rather than the ground side.

Subject: [Farmall] FARMALL H BATTERY DISCONNECT

Long time reader, first time post.
I just bought a restored 1950 Farmall H.  Three days after bringing it home from Phoenix, AZ, I took the tractor to it's first event.  Wasn't I surprised when it had a dead battery and I couldn't even get it off the trailer.
I have purchased a NAPA battery disconnect switch, part # SW181.  The H is positive ground, which is new to me.  My 1953 Super M is 12 volt negative ground.  Anyway, which cable do I install the switch on?  The positive side of the battery going to ground?  I want to be able to park the tractor for several weeks at a time and not have a dead battery when I go to start it.
Thanks,
