12 volt conversion

I recently converted my WD to a 12V system by putting a resistor in series with the ignition coil lead, and using a long piece of #4 or #6 (not sure) wire in series with the starter cable to drop the voltage at the starter to 8V while cranking the engine. The generator is not functional except as a bearing point for the fan belt, and the lighting system is disconnected.

In conjunction with the above, has anyone tried reversing battery polarity from positive ground to negative ground and installing a single wire 12V alternator? If polarity is reversed what effect will it have on the starter?

The starter doesn't care about polarity,it will turn the correct direction. I just changed my WD back to 6 volts. I got tired of replacing ring gears every couple of years. Also brushes in the starter wear out fast. It is amazing what a good starter overhaul (new brushes and replacement of weak springs will do. 12v will cause the bendix gear to turn too fast before it engages the ring gear. I was embaresed to grind the gears.

Polarity has no effect on the starter. You do have to reverse the leads on the coil. If you do the conversion its easy to take an old 12 volt car coil and replace the 6 volt. You can run the 6 volt condenser but I like to use the condenser that goes with the coil.

For my wd-45 I went to autozone purchased igiton coil # 11849 c819 a alternator # 33906 7127 and a voltmeter # 084176 cp7985 all for $52. use only the terminal on back of alternator and get 12 volt battery.Go to negetive ground on battery and switch the two coil wires around then follow wire diagram for the voltmeter.I have put atleast 60 hours on tracktor with no problems and was told 12 volt wont hurt starter.

There is some good info on this site: Go to Article Archives to your left, then scroll down to Maintenance and Mechanical Information. Under that heading you will find "Converting Your Tractor From 6 volt to 12 volt". I have converted my WD, my WD-45 and my brother's WD using all Ford parts. This is the hard way, but I just happen to have a ton of Ford stuff around. I never reduced the Voltage to the starter. These tractors start so quickly now that the starters never get a chance to overheat. I changed them all to negative ground and I use an original Ford resistor wire to reduce voltage to the 12 volt coil. Absolutely troublefree. If I didn't have all the Ford stuff lying around I'd go with the GM one-wire alternator; that's the easiest and cleanest way to do it. Brian G.
