I was looking at a Grasshopper mower with a Kubota 721 diesel engine. It had this little alternator on it.

Has anyone tried retrofitting one of these to a GT? Were there any issues wiring the 6 wire rectifier in? This seemed like a good way to add charging to a tractor.

Much easier to just get an internally regulated one wire 40 amp alternator.  HERE

One wire? I suppose it's grounded. Where does the one wire go?

To your ammeter, or key switch.  If using an ammeter, you'd still need to run it through your key switch to prevent drain when engine is off.  You would wire it to the accessory pole on the key switch.  If you put it on the ignition pole, the alternator may keep the ignition firing even when the key is off.  I am using 2 of these alternators.

I'm running one of those dynamos on the diesel in my golf cart. I didn't have room for an alternator. It puts out enough to keep up with all the lights so that works for me. In the past we have had several engines with those on them and never had a problem. I think they put out something like 14 amps.

I purchased one of those and it didn't last 50 hours. Don't think I'll buy another.

I ran a GM 2 wire on my Sears for a bit when I couldn't afford to get cahrge system fixed, I just happened to have 4 off htem lying around from my hot rod days. Worked well, but bulky and I had an over charging issue. Had it on a separate switch so I could turn charging off/on when ever I wanted

Does a 40 amp altern' work with a GT battery?

 

I'm trying to think where I would run one on a Wheel Horse. I can run it off the pto if I want to turn it off and on with the pto clutch.

Yes that alternator works with the GT battery.
