[Farmall] FARMALL H BATTERY DISCONNECT

[Barney Van De Weert]

If everything on the tractor is OK you shouldn't need the switch- if you leave it parked for some time- I'd recommend a battery maintainer. There are several things I have learned about batteries- Don't leave them sit on a concrete floor, always keep them at a full charge-that's why the maintainer, they only have so many cycles, also an older battery will not take a quick charge- but given a slow charge will still work. When checking the tractor out- connect a volt meter between the ground post on the battery and the ground cable- there should be no reading- if there is you have a bad component somewhere. If you want to know the condition of a battery have it load tested- before that use a hydrometer and take the caps off the cells and check to specific gravity this will tell you if you have a dead cell. Always make sure the battery is up to the ring on fluid if not add distilled water to get them there.

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,
