Hello all,

Its time for me to upgrade our Case to a 12 volt system. We are done using it for the season, and I have it in the garage.

So what I need to know is HOW to do it.

Thanks for any help you folks can give me.
If there is a procedure already on the forumn some where Maybe someone knows.

Thanks
Dave

As I have said before, batteries may have gotten better. I have had my VAC since late 50's and it never would start with the 6 volt b. 1 or 2 turns with the crank would kick it off.
I converted it to 12 volt 10 to 12 years ago with no problems. No more hand cranking and I can see with the lights.

GeoMo,

I am still compiling data, for and against. How has your starter held up? Did you have it rewound? Thanks
Dave

I have had no starter problems. It will start in a turn or two, if it doesn't I look for problem and let the starter cool.
I used GM alt ( 3 wire 70's 80's series).
Changed the key ( need 2 circuits) and the coil.

We have a 52 model we use almost daily and for starting in the winter we found 12 volt to be a big help. We put a 12 volt generator off of a 930 on ours. Required no wiring or mounting bracket changes and still looks original to the untrained eye. Been on for 9 years with no starter problems. If someone has put a dist. on yours you'll also need a resistor to your coil, if still mag you don't have to worry about it

I will go against the grain as I am known to do from time to time on this board. When I bought my '44 SC the 6 volt system was not working at all from the generator to the lights. We use ours plowing snow on public streets, hayrides, parades, farm, etc. and needed good lights and a flasher. I saved all of the 6 volt stuff but converted to 12 volt. Follow all the directions in the conversion information from the YT site and you will be O.K. Be sure to use the specified GM alternator and the protection diode install is critical. Advance auto parts has mountable black lights very close to the original size for about $15.00 each and no modification was required to the light bar/bracket assembly. Good Luck!

Dave,
I'll have to agree with the rest of the gang. I ask the same question last winter & got the same response from these guys.(I have an LA, so it's a tad harder to crank than an SC & they still gave the same advice:) So I cleaned the heck out of all the wiring. (did not replace any of it) Put new terminals on the ends of the bat cables($2) & bought an 8 volt battery(8v are $50---6v are $30). Also had the original alternator rebuilt along with a new regulator($75). The 3 6v/8v light bulbs were $15 each(Wagner from Napa). And she's good to go! Starts great.
We have 6 & 8v batteries at all the farm stores here.
Also was warned that a 12v system will slam the bendix into the flywheel much harder, increasing the chance of busting something.

Good luck!
Steve Moeller

Hey Dave!! Don't do it!! I know from experience, a good 6V battery, (650CCA @ 0) and at least 1 guage Bat. cable will do the trick. That SC starter will spin. Remember, Bat. cable is like water pipe; with age, it looses it's ability to conduct. If the cable & ends are corroded, it can't deliver what the battery has to offer and what the starter requires. Baggsy is 100% correct.

Hey Dave; Any battery dealer will sell a Group 1, 6 volt battery. They are fairly popular. Get a good one. 650 CCA @ 0 degrees Farinheit. Check these numbers closely. Good luck!

I found the process in the articles section.

But if anyone has any tips not listed I would appreciate it.

Thanks

I gotta ask why you're doing it? I can see it if you have attachments that are 12 volt, but from what I've seen on the 8n board, alot of 12 volt conversions just add up to more problems. There's a fellow over on that board that has a good saying..."There are alot of ways to do a 12 volt conversion, and some of them even work!"
