For those who have done it already, did your alternator setup include a regulator? I am looking for a cheap alternator setup on ebay to put on my SS12 for the winter, when I will be running my winch. Do I need a regulator?

:thanku:

Get a GM " 1 wire " alt. They excite at about 2500 RPM's but once excited, they keep charging as long as there running. You can wire a 3 wire into a 1 wire ( same thing actually ), and you could go to the parts store and get 1 for a 1975 Chevy ( pick a model )

Check out some of StLadrill's posts in the JD forum. He added a small alternator to his JD x300 to power the additional lighting for snow removal.

This is a GM alternator on a 112 JD i used to own. It was the only source of electrical power on the tractor. Worked perfectly the 4 years I owned the tractor and best of all was free. My friend had it sitting in his garage. Roger

I wouldn't use an aftermarket ammeter. If they short out ( common ) the amperage will cause a fire, given there wired to the charge circuit. Use a volt meter instead

When you use a GM one wire alternator make sure the ground is a solid connection and check it on a regular basis. The regulator uses the ground wire to check the circuit voltage. If the ground wire connection is bad it can burn up the alternator. I have thought of adding one to my JD 524 walk behind snowblower so I could have lights on it.

Check out suburban12's threads. He has an alternator on his 12 HP sears. He helped me wire up mine on my 16 since I use a winch also. I think my battery is down though cause it still can't keep the battery charged. I used a 3 wire and hooked up a switched positive to excite the alternator to charge. I think suburban12 was able to use existing holes in block to bolt it on, my muffler on my 16 prevented it so I had to cut/weld up new brackets.

Do you mean suburban16? I have seen his thread, in fact it was the one that got me thinking about adding one to mine. Do you have any pictures of your brackets?

Anybody tried this on an old Murray 11-36. It has a vertical c/shaft and looks like it could be a challenge.

I have converted all my GTs to voltmeters from ammeters so it actually tells me what is happening in the charging system. HF sells one for about $10 and I have them in 5 tractors with zero problems in the last 5 years. Roger

Dang, I should have got that instead. Oh well, I'll give the digital one a try anyway. :thanku:

No, look up member....."suburban12". He has a cream and white suburban with stripes and a Chevy bowie on the front. He wired it using a distribution block for adding extra electrical attachments. He talked me through my wiring. I would add link but on my phone. I took pics, but on my camera and laptop is down so can't upload.
