How would you go about jump starting a 6 volt system with a 12 volt system. My 8n still has a 6 volt system, I was wondering how to jump start the tractor from my truck. I appreciate your response.

Thanks

Its better to keep your starting system in good condition and avoid jump starting.A fellow here tried to jump start a late model tractor out in the woods.A friend found him pinned under the rear tire.The tire pinned his head to the ground.The loader dug in and stopped the tractors full weight from getting on him.He survived with an arm broken in 3 places.He must have had a boost battery and jump cables.He boosted the tractor in gear and it came close to killing him.A 30.00 new battery would have avoided this.I saw a battery explode on an 8n years ago when the owner applied the 12v battery directly to a 6 volt battery in the tractor.

Check out tip # 43, plus what Kevin sez. You do need some battery voltage to power the ignition circuit.

But you cannot jump start in this way if your 6-volt battery is too weak to run your ignition circuit.

Whatever you do, do not connect the 12v to the 6v. The 6v could explode.
1 - make sure tractor is in neutral.
2 - turn key on, gas on.
3 - make sure tractor is in neutral.
4 - put 1 jumper lead on a good ground on the tractor.
5 - make sure tractor is in neutral.
6 - put other jumper on the starter post. Starter should spin. If tractor was not in neutral, call 911 cuz it just ran ya over (big grin). HTH....don t. .....

Yep you can jump start a 6 volter with a 12 volter.
Just do NOT go battery to battery.

Make SURE that your tractor is in neutral.
Turn on the ignition switch.
Hook one side of the 12volt jumper cable to the big post on the starter.
Check again that you are in neutral. (We would not want to hear from your kin that the tractor ran over you!)
Touch the other clamp of the jumper cable to a good ground on the tractor -- i use a foot peg.
Polarity does not matter -- starter spins the same way either polarity.
Do NOT hit the starter button -- that will keep the 12 volts off the 6 volt parts on your tractor (battery/generator/regulator/lights/coil)

You do need enuf juice in your 6 volt battery to run the sparkies.

Ground negative jumper cable to the frame of tractor and touch positive to bolt on starter (where starter cable is connected). Make sure it's in neutral, starter switch on, etc. Starter will spin as soon as you touch with cable. At the risk of being repetitious, make sure it's in neutral before you start this process.
