9 volt battery hooked to dizzy to get a tractor to run

This is probably the looniest idea/question I've come up with.

I have a Farmall H. Its in my list of things to restore, but its a few pegs down in the line up.

The starter is bad, so I use a hand crank to get it going. At the present time the Generator is not working either. So when I run it to move it I have take a battery to it. No big deal, as its not a tractor that I'm using.

I like to start it from time to time for the fun of it, so that time to time gets extended to when I feel like lugging a battery and cables around.

I have another farmall H that is restored and I know that it doesn't charge much at idle, apparently that's pretty common.

The unrestored H Starts pretty easily with a battery hooked to it. 6 Volt System by the way.

So this is what I was thinking. If I fixed the generator and got it to charge, (I want to learn to do that anyways, I've got another one to do as well) could I use a 9 volt battery, you know the small one in a smoke detector, to get the tractor running and then when it reached the correct RPM for the Generator to provide a charge then disconnect the battery.

So, with that said, I'm basically using the small 9 volt battery in providing power to the distributor to get the tractor to fire at the lower RPM and get it to the operating speed the generator needs to provide juice...

So what do you all think. There are probably reason's why this won't work, and I'm just not knowledgeable as to why. There are probably reasons some of you won't run a tractor without a battery. I've heard something about that before.

Thanks

No.

A small "transistor radio" battery does not have the capacity to supply power to the ignition system of your tractor.

A typical Kettering ignition system draws 3 - 4 Amps, WAY more than a 9 Volt "transistor battery" is capable of providing.

Also, running the ignition from a generator designed to be connected to a battery WITHOUT a battery is not a good idea! If it is a cutout system it will put too much voltage into the ignition system, if a system with voltage regulator it will tend to burn the regulator's vibrating contacts.

agree, need some amps to power it up which that little thing cant do.

Just put a magneto on the tractor.

I thought this would probably dumb question, I guess if I come across a mag I'll get it. I can just continue to haul a battery to it when I want hear it run.

Thanks for setting me straight

The ign system will be like a dead short to that 9v battery & the voltage will drop so low it won't produce a spark. Put a mag on & you won't need a battery.

A pair of lantern batteries like used in the lager old flash lights hook up in so as to have 6 volts but more amps would probably be enough to run it. But no matter what it is not a good idea to remove a battery from the charging system with it running because then the V.R. sees zero volts and then does its best to charge to the max and that can let the smoke out of thing

Most of your ignition systems pull about 4 amps so your 9V smoke Detector battery won"t give you spark for very long!

if you buy the battery jumper box, lighter than hauling batterys, can plug in house current to recharge, even with 6-volt system, can give qwick jump start. comes in handy with dead battery out in the field also. it has saved me many of times.

Rebuild the starter and generator yourself, or take them to an alternator shop. Usually, a general cleaning and new brushes will correct the problem.

Seriously?

Yes, I know Pretty bad.. I've learned my lesson not to let the crazy thoughts/ideas out of my head.

Dream on, your 9 volt battery wont put out 4 amps.

I cant stop laughing.You mean 3 D flashlite batteries would crank my tractor, Dufus is every where.I could save money by using 3 AA penlite batteries.

Leave the battery in the smoke detector....

What if you were to put a small 6v lawnmower battery on it. Alot lighter to carry around, and with sufficent power to supply the system.

When the points are closed, the current draw is so high it would kill the little 9 volt battery before you could start it. Once running it would be ok, because the amount of time the points are open versus how long they are closed coupled with the collapsing of the field in the coil producing back EMF will drastically reduce the current required. Now that I have explained why the 9 volt battery will not work, what will work is getting a battery holder from Radio Shack and using 4 D or C cells in series, or one of the 6 volt lantern batteries. I have done that and run tractors several hours on the 6 volt lantern batteries. You can even buy rechargeable lantern batteries or C or D cells if you chose to go that way.

o one said anything about cranking it with the batteries, they were asking about powering the ignition.
