My Dad"s Super c battery has been sitting for over a year. I want to charge it or determine that the battery is no longer any good. I have seveal questions that I need answered here because I have gotten conflicting opinions from friends, neighbors and O"Rielly"s auto store. Do I hook up the charger + to + or backwards? Do I need to disconnect the battery from tractor before charging? What polarity is the generator on the tractor charging the battery? The tractor is kept on another property and not run very often. I would like to keep this from happening in the future. Is a cheap float charger effective in this situation, or do i need the more expensive digital mantainence charger. I know this is a lot of questions, but I know they will be answered correctly here. Thanks so much for all of your help.

Pos or neg ground make absolutely no difference in charging. ALWAYS pos terminal of charger to pos terminal of battery and neg to neg!

Do I hook up the charger + to + or backwards?

As posted below + to + and - to - from charger to battery

Do I need to disconnect the battery from tractor before charging?

Battery can stay in and connected to tractor when charging

What polarity is the generator on the tractor charging the battery?

The tractor originally was Pos ground meaning its Pos terminal was frame grounded. The charger so long as its + to + and - to - charges the battery correctly

To be safe and once the battery is charged, Id Polarize the genny prior to starting the tractor.

You will be using a 6 volt charger, of course.

Finding a float charger that outputs 6v can be a challenge.

Thanks so much for your replies. I will charge it and see if it comes back to life. I doubt it will. Should I use 2 amp or 10 amp?

As others have stated always when charging (or Jumping) any vehicle always hook + to +, and - to -.
If a vehicle is positive ground or negative ground, that only means how the battery is hooked up to the vehicle. It does not change the polarity of the battery. On many shematics we were taught to believe ground is negative. On vehicles, ground only means the wire leading to the vehicle's frame.

When jumping or charging a battery when you hook negative to positive you will double the voltage of the system and can destroy all the electrical components on that vehicle or both vehicles more so when jumping. When you hook a battery charger up positive to negative you will get lot of arcing and the charger doesn't even have to be plugged in for this to happen.

We have several JD's with 6v positive grounds. From experience, disconnect the cables from the battery to the tractor, then connect positive to positive and negative to negative on the battery and charger. Trying to charge the battery without disconnecting the batter cables from the tractor will be unpleasant. BTDT

Your advice makes no sense.
The battery explosions you alude to occurred because somebody jumpered chassis to chassis instead of - to - and + to+ .

I don't understand that post either, I charge my farmall 6 volt right in the tractor, +to+ -to- never had any problems, why did they use positive ground back then?

Connect the charger exactly as you do with any other item. + to + and - to -. The only thing that no one else has mentioned is that when you jump start an item with reversed polarity is that you do not want the vehicles to touch. I charge mine with a 10 amp automatic charger. It does very well for me. I bought my 6 volt battery new in Sept of 2008, been going strong ever since.

Forget how it is ground makes no difference as to what side of the battery is ground because you ALWAYS hook a charger up + to + and - to - NO MATTER what. The term + or - ground is one of those things to many people over think which is what you have done

The two Shumaker float chargers I have will automatically detect if the battery is a 6 volt or a 12 volt and set itself accordingly. I am using one on a 1940 H with original 6 volt cut-out relay, positive ground system, and an identical charger on a 1940 M with 12 volt alternator conversion. The charger just doesn't care one way or the other.
