A $60-$70 single wire Chevy mini alternator will work awesome if you have a pulley to run the belt.

Member http://gardentractor...-nascar3244888/ put one on his Lombardini diesel repowered Bolens 1050 and it does a great job.

I put one of those little $70 alternators on my GT and it quit in less than 50 hours. Still looks like new. I have to say it did work good for a little while.

Check on eBay.  I have a $10 one on an Onan that is working fine.  Told a member about it and he got one to get his Onan working also.  Anyone interested PM me and will get the co name, etc.

well here's the story put a brand new battery in there and my buddy sold me schumacher battery maintainer only used once 1.5 amp well according to the directions hooked it up with the blk/whte wire to the positive and blk to negative and there's three little LED lights that when on starts out red showing power then a amber one shows when its charging then green when its fully charged.......well i get none of that unless i change the wiring around just the opisite what the directions told me to do.........then it shows its charging ......then i'm scratching my head saying WTH? then i come out 2 hrs later there's the amber light blinking..indicating there was a trouble of some sort so gone through all the connections retightened things a 100 times over and same results haven't had time to contact the manufacturer and say whats up with this .....so i'm a little frustrated with this

well 2 of those alternators is still cheaper than rectifier/regulator for my Tecumseh OH 160 from what I could find of course I got the hard wired version seem harder to get too

Well once started, battery not needed for much, maybe lights if at night, so no big draw on battery. That is mostly for starting. Would think just a battery charger on the battery occasionally would give it enough to start and should run long time on same charge.  Lots of old-time motorcyclists used to do that with racers, run till they missed, then change to newer charged battery and go back out for more racing.  I suppose one of those better maintainer's would keep it charged up and be plugged in all the time, but it won't charge battery that is low they say, just keep it up to full charge once there. The cheap ones aren't for long term storage that way either, need better one with de-sulphator and other cylcles to leave on all the time. They also shut-down when not needed. You use the pto on tractor?  Suppose one could run a gen off the front side and mount it to bolster on front, OR, run a shaft out to a bracket with pulley and gen set-up there? OR, wonder if one could use ONE belt on pto, then use the other sheave there to run the belt for  a gen underneath?  OR...just save up and get the right stuff to fix it, take the LUMP in head and pocketbook, be happy!  :poke:

If you you halfway handy with electricity try this. A whole lot easier to replace your rectifier.

Schematic.

The 1 wire alternator will also work fine and put out alot of power. The one I have on my 4 wheel drive is 35 amp.

It should,There are either 3 or 4 wire.

2 wires are the AC side 

1 wire is 12 Volt out to Bat.

1 wire is ground or a 3 wire would be case ground

One wire alts just need the lead going back to the Pos battery cable or connector.  ON a big tractor it will not charge till revs come up to I think 1200 rpm or so, then it kicks in and stays on. OR, can hook up an exciter circuit to small wire terms on alt that need a 12 volt start source to make it start charging at any rpm. This tho requires a diode or such in that line, so alt does not discharge the batt when tractor is off.  Not sure what one does on smaller rigs.

Just throw another newer style regulator on it. As long as it's an AC/B+/AC regulator and up to the amperage ( should be a 20 amp), it doesn't matter what it looks like. I run one on my Sears with an OH160 and an electric winch.

 

I use this type from evilbay.
