12 volt conversion

I am converting my super m over to 12 volt. I was told I could have my generator changed over to 12 volt, so that is the way I elected to go. Is there a wiring diagram on here that shows the way it will need to be wired. I want to double check myself to make sure I am doing everything correct.

Do I need the ballast resistor if I install a 12 volt coil? I am changing to a 12 volt coil and 12 volt regulator.

If the coil says ---12v for use with no ballast resistor--- then it will be fine. They are internally designed to run on the full voltage. (number of turns of primary wire) Jim

I converted mine about 7 years ago. I had the generator rewound to 12V, changed the regulator to 12V, put in a coil from a Kohler 12 h.p. engine with an internal resistor, switched the bulbs to 12V, switched the battery cables to a heavier cable and made the system into a negative ground. Because I switched polarity I reversed the wires on the ammeter and made for sure the coil had the negative side going to the points. Mine finally this last summer had the battery replaced. It has been trouble free. I converted a friends H the same way plus added electronic ignition to it. It starts as soon as the button is pushed.

I was wondering about the ballast resistor, what is its purpose?

The ballast resistor reduces the current through the coil and points down to what is typical in a 6 volt system. It needs to be installed in the hot wire somewhere between the switch and coil away from anything flameable as it produces significant heat. It permits use of the existing 6 volt coil along with increasing the point life greatly. Hope this answers your question, Hal.

If it helps, the wiring should be exactly the same for a 12V generator with regulator setup, as a 6V generator with regulator setup.

Basically if you kept track of what went where when you took it apart, just put it back the way it was...

However, the main reason for going 12V is to get rid of the unreliable, maintenance-intensive, generator/regulator setup. You're not eliminating that, so you may as well have saved your money and stayed 6V, IMHO.

The generator/regulator setup ruins batteries. That's why 6V batteries don't seem to last while 12V ones charged by a modern solid-state alternator do.

I also always changed the voltage regulator to 12V. Maybe some of the more knowledgeable electrical posters can explain if its necessary.

You are correct, I made that unwarranteed assumption. Jim

There is no need to change much if you switch bulbs to 12v and put a ballast resistor in the coil feed from the ignition sw. The wires should be exactly the same. Jim
