I'm considering changine my oc-3 to a 12 volt system. just wondered if anyone else has done this, and what your opinions are on it .  My generator needs rebuilding, so should I put money into that or just go the the 12 volt system.
all thoughts appreciated
thank you

It's an easy conversion if you are changing generators or going to an alternator. If you go to an alternator, get one that fits - don't butcher up the hood!

The starter will enjoy 12 volts just fine with no problem. In fact it will start so much quicker, it will create much less wear to the starter.

If you have a mag, you have no ignition to worry about. If you have a distributor, put a balast resistor in the line to the coil.

Don't forget to change your light bulbs to 12 volt!

Thanks for the info. I didnt think about it not fitting under the hood. any recommendations as to what alternator to use?  I do not have my motor in right now, it will be getting rebuilt thruout the winter. I'd like to get it all setup and running before I put it back in.  

Thanks for all the great info.

I am in the process of changing my OC3 over to 12 volt also.  As you, my generator was not working.  Took it to the local auto electric shop where they rebuilt it and provided me a 12 volt voltage regulator.  They told me the generator would generate any voltage and that it's the voltage regulator that controls what voltage system you have.  As Blake mentioned, I have a magneto ignition system so no problem there and I have no lights on my tractor so nothing to worry about there (but if you have different - follow Blake's advice - simple fixes).  Only thing on my tractor that needs the battery is the starter so I'm in good shape.  I'm really looking forward to having an 12 volt system!  By the way, I elected to just rebuild the generator and get a new voltage regulator so I could use the existing mounting hardware and wouldn't have to worry about rigging up mounting hardware for an alternator.  Good luck!

Thanks for all the info.  I think i'll go with the 12 volt generator/ regulator  setup. that way everrything will fit ok, and look normal
thanks everyone.
