Is there a way to jump start a dead 6v battery on my Farmall H? It is completely dead and my charger won"t charge it.

Often if a battery is like totally dead but not internally shorted n it has sufficient electrolyte, it can take a good while before she ever starts taking amps so leave it on high charge a while n see if she ever starts drawing current. Sure you can jump it buttttt ttttt a totall dead battery may be like an amp suckin drain so you might (if it has a good charging system) be able to jump the STARTER ONLY n if she starts a good genny can supply the meager 4 amps required to power up the ignition.

Id take that battery to a shop for a good test n let them try n re charge it n load test it. If your charger is only a wimply lil trickle charge Im not sure if it will ever come to life. I set mine on a high charge rate n let them set n cook a while n finally once they (if ever) take amps i back it of for a good slow deep charge.

See if theres electrolyte above all the battery plates and that no cells have a different or gray milky color??? Give her more time on a charger,,,,, ,,,try n jump start (AT CORRECT POLARITY) ,,,,, ,,,,and/or try to just jump the starter n see if she will run????? Will it pull start?? (requires a good genny like Jim mentioned)

You should have the battery checked to see if any of the cells are dead and see if they can they charge it. Hal

If your battery is completely dead and you have a distributor it won't run anyhow. With a mag it won't matter.

George, I differ in this, a generator equipped tractor, with an operating system can be pull stared with a dead battery. The gen is self-exciting at startup (pulls in the cutout relay) and given 40 to 50% of High idle will start right up. JimN

None of mine will. I have a couple with altenators that will, but none of mine with generators will hit a lick with a dead battery on them. I have tried many times.

Yo Jim, I can back up your theory from yearsssss ss of experience lol. (Gotta have a good working charging system fer sure) We were in an old truck late at night headed back from a farm auction in Sikeston Missouri and the genny brushes were worn so low she stopped charging n the battery went so dead it would totally die. We lucked out n she died on top of a big hill,,,,, ,, we removed the genny and placed a kernel of corn between the brush hold downs n the brush, gave her a good push n once she got rolling (just at bottom of hill whewwwww) she began charging enough to power the ignition wooooo hooooo oooo lol. Then we got into a small town (past midnight) and found a small junk yard where my buddy crawled under a junk car with a crescent wrench n pliers n got a genny n we robbed the brushes n installed in or truck n made it home. The wives never believed that story about why it took us all night to get home !!!!! !

I'm going to add a bit of info.
If the charger is 12 volt, and that is the reason you can't charge it, pull starting the tractor will more than likely do the trick.
If the battery is dead from lights or ignition left on they sometimes look to a good 6v charger like they are not connected (even if they are) jumping another 6v battery to the dead one + to + and - to - will charge the dead battery from the live one enough to let the charger know that there is a battery hooked up (might take a half hour). A 6 v battery can be charged with a 12 v charger if a 12v light bulb (headlight is good) is placed in series with it From neg of charger to light terminal, then other light terminal to neg of battery then pos of batt to pos of charger. It will not charge very fast, but it will.
If the tractor is one with a solenoid, or has two heavy terminals on the starter switch (some mechanical starter switches cover a copper terminal into the starter and do not work for this) the tractor can be jumped safely by commecting 12v battery (in car or not) to the tractor as follows, chassis of car/truck to chassis of tractor (polarity does not matter in this old Farmall application, trust me on this) then from positive to the switch terminal going into the starter from the solenoid or starter switch. There will be pretty substantial sparks, because you are connecting hundreds of amps. Be sure there are no open fuel containers, or fuel leaks. The positive cable should be carefully maneuvered so as to only contact the starter terminal I indicated, or the high current can damage things. JimN

Jeff - As long as the dead battery does not have an internal short (ie. the battery charger does nothing when connected) simply jump the tractor the normal way. Once the engine starts keep the RPMs a little above idle - the generator will provide sufficient current to run the ignition even after the jumper cables are removed. (Of course if the tractor has a magneto it's run fine even at idle w/o the battery...)

If the battery IS shorted, disconnect the ungrounded battery cable and use a zip tie or similar to keep the ungrounded battery cable terminal from grounding on anything. Now connect your jumper cable to the ungrounded battery cable terminal and proceed as above.

IMPORTANT! Observe the tractor's ground polarity when jumping. Connect only + to + and - to -; even if the dead battery has been disconnected or removed!

chances are if you cant charge it with a charge, your battery is shot,,I dont think that a jump will solve your troubles,,

IF your charger has a "booster" on it, you can sometimes boost it enough to get a small excitement into the battery to get it to take a charge,,

if that doesnt help ,, well its time to bite the bullet and get a battery,, they sure dont last as long as the used to or should, pat
