2015 6.7 Lariet do anybody know how many Amps the heavy duty alternator is, and how many Amps it can supply continues. Frank

Regarding alternator belt squealing. Mine only does so with a depleted enough battery and a cold damp belt and with my voltage regulator asking for 13.8v plus.
My solution is to lower regulator voltage till things warm up. I can get 120 amps from a single v belt if it is tight enough. But that is undesirable for water pump bearings. 75 to 80 battery charging amps is possible at normal belt tightness with all loads off other than fuel pump and ignition. I can run dual v belts but have issues with harmonics as matched belts are not so matched and my ac compressor pulley does not align perfectly anyway.
My v belt is old. Should likely change it or at least have a new spare instead of a used one.
