super c 6 volt to 12 volt

Thinking of converting my 53 sc to 12 volt.what is the best route to take.I don't want to mess up any of my tin work.thanks

If you do a search you read about conversions all day.

The factory location for the generator isn't even close to any tin and should be setting right down low on the front of the left side of the engine. Don't know why you think you need 12 volt starting power on the 123 cu. in engine as 6 volt is plenty for that engine. My 6 volt Super C is one of the cold weather tractors I can count on to start when it gets well down below freezing, Hal.

Use a Chev 3 wire alternator form say a 1980 Chev pickup no AC no power any thing. Cost is around $45 plus a $10 core at O'Reilly's auto parts and it has a life time warranty on it. Flap the generator bracket and then you can use a piece of all tread to mount the alternator.

Using a Hitachi 14231 aternator, use the same bracket but use a 3/8" threaded rod (grade 5) to go through the brackets to hold the alt in place. Use 3/8 pipe to make spacers to allow solid positioning. Attach the Big out put terminal to the amp meter (after reconnecting all amp meter wires to the opposite terminals to correct the reading with the different polarity of negative ground) on the terminal going to the lights and ignition sw. Connect a # 12 wire from that same big terminal to the S terminal on the alt (use a insulated 1/4" spade terminal this is a very short wire). Next run a #12 wire to excite the alternator from the L terminal (also insulated. It needs to have one of the following in series with it: A diode from radioshack, or salvaged from an alternator or? it needs to be of about 3 amp capacity or better, and placed so the current only flows toward the alt, Band end toward alt), or a side marker lamp (not LED), or a 10 ohm 10 watt resistor. these prevent the alternator from keeping the ignition on when you shut the tractor off. The other end of this wire attaches to the ignition switch terminal connected to the coil.
Next use a ballast resistor From a mid 1960s Chevrolet at the coil to allow the use of the original coil. wire it in series with the original wire. Reverse the coil connections to assure that the Negative coil terminal is connected to the distributor, and the positive is connected to the ballast resistor.
Replace the light bulbs with 12v of the same wattage, (or LED replacements much brighter).
The Hitachi is just reliable as a stone, and tidy. Look in the archives for Hitachi and you will find many pics. Jim

i just converted my 53 sc to 12v with no change to tin work. i used bob m's wiring diagram found on the web. used an delco alt and made my own brackets out of 3/16s steal. installed a warning light. I have extra one if you need one ill make you a bracket like i made and will send you one if you want to go that route

you have to user a 12v coil and i had to modify the brackett a little fot it to fit and change your 1133 light bulbs to 1143 light bulbs if your using the teardrop loghts

and be sure to attach your ground wire to a starter bolt. i found out the hard way

You must just be looking for a project because a Super C will crank right up in any weather on 6 volts assuming your cables, starter and gen. are good.

If you attach the ground to a starter bolt right away, you don't need to go to 12 volt.

When the battery is shot and the generator is shot, it's CHEAPER to go with 12V. You can get a Delco 10SI alternator around $40, and a Group 26 12V battery for about the same as the 6V would cost you.

Generator work will run you about $100, and a replacement generator is $150+. Add on another $30-$40 for a new regulator. You're well into the $200 range to replace everything, and you haven't even bought a battery yet.

The Delco 10SI will fit right on a Super C no problem. You really have to try *HARD* to make it look like a hack-job install.

You can drop an air on a C without cutting hood or nose, just
make your brackets.

When I bought my c it had no Genny, and a boogered up idler
pulley to keep belt on. Had no battery either. As others said.
When no battery or gen present, salt and small truck battery is
cheapest fix.
