Converting to 12v what alternator to get

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I will vote for Alternator conversion. Yep the old 6 volts work good most of the time. its usually in extreme conditions or poor maintiance that they let you down. I want to convert my D17 from 12 volt positive ground Generorator to Negitive ground with new alternator. It is not charging properly and I see the previous owner put in a new voltage regulator. I have had real good luck with the alternators on the WD series tractors.

	Running 12V's through 6V field coils makes the Starter motor violent. Busted or cracked nose cones, torn up ring gears, etc. are just a couple of the issues. I'm not saying the 6V Starter won't handle the 12V's, you're just better off changing the Starter over to 12V so the Starter motor engages smoothly. The effort and money involved doing the Starter CORRECTLY saves from splitting the Tractor to renew the ring gear down the road. And ya know it always happens at the worst time! Plus, with the nice smooth transition to the flywheel, all components will survive another 30 years or more done right.... Steve@B&B

	When I was young and dumb I switched my ca over to 12 volt. It took about a month an the starter broke. After talking to a few members here I learned that the issue wasn’t the 6 volt system but the small #4 cables the previous owner added. I put it back to 6 volt 20 years ago . I haven’t touched the charging system or replaced the battery since. It starts right up every time. Matter of fact I can put it in first gear and use the start to run it down the driveway and raise the hydraulics at the same time. It works very well.
	Thanks & God Bless Dennis

	Another major issue is parts for the old Prestolite and Delco Generators, are mostly distant memories where one can have windings rewound but a failed armature will likely end up just junk as parts are NLA. Spoke to the guys that used to rebuild my starters and alternators, generator parts are next to non-existent anymore with junk coming out of Asia to repair them with so they quit.

After talking to a few members here I found out that the issue was not the 6 volt system, but the small #4 cables the previous owner had used. I switched it back 6 volt with the right cables. That was 20 years ago. I haven’t had to do any repairs to the charging system or replace the battery. It works so well that I can put the tractor in first gear, raise a mount plow and run it down the driveway all of the battery.

	Half true Dave. There's still good USA made parts for the Delco's. Just gotta' go to the right places to get em'. I have all my arms rewound no problem. Some come in pretty toasted and could possibly be junk, but most can be saved. I've done em' a zillion times. You're right about the Prestolites and Autolites. Parts getting real tough for those units. They're in the same catagory as Terranasurus Rex! LOL! Steve@B&B
