Dead battery, how to jump

sonicblis · May 23, 2015

I left the key on and killed my 6v battery. I bought a new 6v battery at NAPA, attached it via jumper cables to the battery in the tractor and tried to start. The starter just clicked which sounded to me like the new battery was discharged. This is a totally valid way to start the tractor assuming the battery I'm trying to use to jump start the tractor is good, right? I don't have the original starter I don't believe, but one with a little white button instead. The white button is what is making the clicking sound. I'm going to test the new battery to confirm it is discharged and charge it, but I just wanted to check that the older 6v system doesn't have some difference I'm not aware of from a typical 12v car system.

You know, I was reading another post and saw that the wires need to be nice and thick. My jumper cables have a wire that's half broken and I'm gonna see if that's the issue.

No, that's not how to do it. The jumper battery is spinning the starter while the battery in the tractor is providing current to the coil. If the battery in the tractor is dead you have no power to the coil. Charge it or replace it with the new one.

If that battery is really, really dead your new battery won't have the juice to start it - you are just pulling down your new battery. Why try to jump it anyway if you have a new battery? You will run into a situation where you over-work that generator and it may not stay running because the voltage isn't enough in the system to keep the coil hot. Just put the new battery in.

If it is some place you can't get to you need to take the cables off the bad battery, use jumper cables to attach the cables to the new battery, and set the new battery on the running board with you. I have done this to get a tractor/combine someplace easier to put in the new battery. It isn't always easy to get a good connection with the jumper cables.

Yea, you guys are definitely right, it would have been ideal to switch them out. I was hoping to shortcut the process so I could finish a job today. I ended up getting some new jumper cables, stripping the old ones and making mega cables. I hooked the new battery up to the old one and she started up. I greatly appreciate the tips and suggestions. This tractor has a front distributor.

You are creating much more work for yourself than needed. As the others said, if you have a new battery, just replace it in the tractor and forget about trying to jump it. Have battery checked to see if it will sustain a charge under load. Take to your trusty local starter/alternator guy in town and he can bench test it usually for free. Pictures will help us understand what you are referring to about your starter. Even if not the original, a replacement would be almost identical unless someone cobbled up the system with their idea of what 'should work' theory. You will want to polarize the generator after you connect the battery so report back here...
