John, my 4903 has an altenator mounted under road air. I wondered what it was for since their is no wiring and it is not in the book. Big john

OK,it's a 48 volt alternator and it was used to provide power for the A/C condenser fan. Roll Eyes
The later mpdel GMC Buffalo's used a 24 volt condenser fan motor so the extra alternator was not needed.  Grin

I know the 4106s used hydraulic motors to operate the condenser fan.
