APU Alternator help - TK Tripac, yanmar TK270M

I'm trying to find a inexpensive 120 amp alternator for my TriPac but I'm having issues finding one.

The outside of the alternator has a badge on it, says Thermo King, P/N: 2E00204G02, Service P/N: 42-367, Current:65A Voltage:14.5v yada yada.

I asked a dealer if they had the part and they said the new part number is 45-2671 and its $311.50!!?!

Surely there are cheaper ones that will fit, my old one has a fan and pully still so I could pull those off and put them on a new one if needed.

Engine is a Yanmar TK270M - year is 2012 I think.

Eyeballing it I think I've found some Bosches that will fit it but I'm not 100% sure.

Thanks for any assistance, links or anything that will help me track down the proper part.

 

do you have the part # or where I can go? which engine did you have? I have seen the DB electical ones, but I can't find any of them willing to say it interchanges with any of the part numbers I have.

 

I ended up getting a DB Electrical ABO0370 off Amazon for $88 bucks. It's 120amps, plugged right into my old connection.

I was going to do the conversion as its a very common Alternator fitting, but I did not have my soldering set, crimpers etc with me so I didn't do the conversion.

I also learned that if you are not careful, some of the shafts are too short to fit the old pully from the original TK alternator, probably could find a new pully that is inset that is the same diameter as the old one.

I did have to use the old fan and pully on the one I ordered as my unit turns ccw.

Now my other issue I'm having is when I turn on the AC, it shuts down and gives a ALT code.

If I just run the APU though I do not get the code. I believe I need to clean all my ground connections and reconnect everything up to see if it fixes it.
