Correct TM for this alternator?

[ckid]

I downloaded TM9-2920-225-34 for troubleshooting the generator assembly on my deuce. Mine is AMA-5108UT, and the TM only covers the 5102. Is there another TM for the 5108, or is troubleshooting the same for both models?

Water and dust proof alternator for use on most M-series vehicles such as M35A2, M35A3, basic and A1 HMMWV, M39A2 series, M809 series, M939 series, M151, M715, etc. Also used on other types of military equipment such as forklifts, loaders (John Deere 644EZ), etc. <br> <li> Output rated 28 Volts...

"NSN 2920009092483. Prestolite p/n AMA5104UT, Military p/n 10929868. (old p/n's A0013002AC, A0013002AF, AMA5103UT, and AMA5102UT have been superseded by AMA5104UT)."

I couldn't find any mention of the 5104 in the TM either. The 5108 (which is marked as "unavailable" by Prestolite/Leece-Neville) is listed as a cross on some of the suppliers websites for the 5102 and 5104.

But, this discussion-

Great alternate alternators batman!

Long story kinda short... My alternator starts acting up in the duece I.E. voltage in the green, then yellow, then green again. Sometimes it starts out in the red, then green then red etc... I figure it's the voltage regulator based on threads I've read. I have a spare engine so I figure...

implies that the guts of the 5108 (which is also know as a L-N 3002AE) isn't properly covered by the TM.

Not a lot of help, sorry.
My personal guess is the alternators will interchange and the manual will work for external troubleshooting, but not to depend on the manual if your trouble shooting leads you to start disassembling it.

Crap. Army has a TM for tying your damn boots but not this...

Oh well. Thanks for that info. I'm suspecting a bad regulator, but don't know for sure. Now I wonder if something like this (https://www.easternsurplus.net/PartDetails/5455/HMMWV-Voltage-Regulator) will work on this particular model.
