cub 12 volt conversion

[grizzreds]

Hi all. I have been reading about the 12 volt conversions for Cub tractors. My question is what about these 1949 series with a Magneto instead of a distributor?

Thanks Ron

The magneto is makes its own voltage and is not affected by a change from 6v to 12v or 12v to 6v!

Having a tractor with a properly functioning magneto, and a hand crank, then you do not have to have any battery to run!

If your tractor has a battery powered starter, use a single wire 12 volt alternator. The alternator is only to keep the battery charged and power the lights.

Magneto as Sam indicates, self powered.

I guess I didn't make myself clear. I apologize. I have a good working knowledge of the magneto and it's application. My issue was that I have not see or found any videos of the 12 volt conversion on a tractor with a magneto, only distributor and coil. I was wanting to see if someone had done one.


Thanks.

Do you currently have a six volt starting/charging system on your cub?

It's fairly simple. Use the single wire 12 volt alternator diagram. Eliminate the wires to the ignition switch and battery powered distributor.

Following is a how to.

There isn't all that much to wiring a Cub with a 1-wire alternator, so you really could do it yourself.

All the complexities of the generator/regulator are gone, so beyond the main battery cables, you really only need:

1. Wire running from the post on the starter to the - side of the ammeter
2. Wire running from the + side of the ammeter to the ignition switch
3. Wire running from the other terminal of the ignition switch to the + side of the coil
4. Wire running from the - side of the coil to the distributor
5. Wire running from the + side of the ammeter to the fuse
6. Wire running from the other terminal on the fuse to the power terminal on the light switch
7. Wire running from the front light terminal to the front lights
8. Wire running from the rear light terminal to the rear lights
9. Wire running from the + side of the ammeter to the alternator

If you have a magneto, you actually only need 7 wires: Skip wires 2, 3, and 4, and run a wire from the ignition switch to the ground-out terminal on the magneto.
