A formerly used, but now not needed hole left in the battery box for the last few years of production is weird? :shock: Have you ever looked under your left foot while driving? They never got rid of those two holes in THIRTY PLUS YEARS! :D :lol:

Old habits are hard to break, plus it makes the boxes backwards compatable.

Guess the extra hole makes a good vent.

Where do you get them & what sizes are available? I need something like that for my Super A's. The stock configuration is a short ground cable that bolts inside the battery box; I have never had much faith in that setup. I want to ground down on the frame somewhere, while trying to hide my modification!

Two types available here, Al. Battery cable or bonding strap type.

A braided strap is factory on your long stripe. Not sure when it changed, but it is the ideal way to ground the battery and works to keep the battery in place too (in the front).

You can get them at NAPA, but my 77 has an IH part number on it. 356092R91?

Lately I have taken to a rubberized paint for the inside of the battery box. When I paint it I put a big round washer in the hole that will be for the ground strap and use an unpainted bolt for that one. Can't hurt to run a tap through the holes too. It is essential to have a good ground.

Hi,
Here's a pic Ricky, and anyone else that wants to see the 6 volt battery original cables, at the left lower part of the page. It's from the owner's manual. Click on the pic makes it bigger. :)

Got it together tonight, the 26 R batteries had the positive on the left side, I got a plain 26 with the positive on the right worked good. Still nervous about how close the cable is to touching the front of the battery box so I scotched it with a piece of rubber in the front and up over the top about 2 inches. My 77 I fixed tonight had a braded cable to the front that was destroyed I robbed the 78 of its rubber type that was mounted to the rear. I did notice the battery box lid has a tab that mounts in front of the battery box front, unlike the older style battery boxes.

My need is education! With the 6 volt positive-ground system of my 1955 Farmall Cub, must I remove the battery connectors when I want to charge the battery? I always do, just to make sure that the reverse polarity of the Cub's electrical system doesn't conflict (i.e., sparks flying, starter motors and generators burnt out) with the charger which I use with the + going to the battery +, - to - on battery.

I've never attempted to start the Cub with the charger on, but wouldn't that just be a disaster?

As is, I have a quick disconnect on one side of the battery and I pry off the other one.

Would someone tell me I'm right or wrong...and why?

Dick, no need to remove the cables to charge the battery. Depending on the clamps it is often easier to connect the charger with the cables off. Your call. Not a problem to start the tractor with the charger attached. Many chargers have a booster setting to do just that.

Positive is always positive, negative is always negative. The Cub is it's own little world (planet Cub) as far as electricity goes. You get to pick which way "the world (planet Cub) spins" by deciding which end of the battery gets grounded. On a vehicle "ground" doesn't mean the same thing as it does in your house. Positive ground and negative ground are functionally equal. The electrons just flow in different directions. Think of in the U.S. we drive on the right side of the road. The British drive on the left side of the road. We both get to where we are going with out difficulty. Or SAE and Metric wrenches, or phillips and flat screwdrivers............

I think you are equating touching a Positive terminal to ground, on say your car with a negative ground system and getting sparks; to there being some disaster if you look wrong at your Cub just because it's positive ground.

I was able to finally get Bigdog's cable routing post into the "How To" forum so it is easier for some to find. viewtopic.php?f=140&t=82170

Thanks to Arthur Luke and Big Hoss for finding it for me on the manual server.

Starting with the charger pluged in might overload it if not made to be used that way. Just unplug and crank away. If no start, plug back up.

Hi,
Dick, here is a pic of the starter post that you asked about, with the battery cable, it's at the nut on top of the starter. Hope it's ok to put it on this post. :)

Thanks, Glen, the idea being that Glen doesn't even take the lid off his battery box, just clamps the battery charger's "-" to the starter post, and the charger's "+" to a good ground wherever, and it charges his battery. Nice, for me, to not even have to mess with the battery. And I'd take the charger clamps off before starting. Thanks, all.

Thanks for the tour of auto/tractor electrics, Scrivet. It reminds me of the time when I bought a Daihatsu jeep, extremely used, in the south Pacific on an island formerly a British claimed colony. The guy selling it to me kept correcting my driving as I tested it, gave me a speech about how to remember which side of the road was mine, etc. When I drove off, having been so educated, I saw that he was waving at me to get over in the correct lane -- I'd automatically reverted to USA driving. It did take constant correction, for a week, from an often frightened wife, before a got the hang of it.. Let's hope I'm a bit quicker on the Cub electrics!
