5.7 Alternator ???

Thanks for your input and to Joe for a total clarification of charging system.

My wiring is exactly like on Joe´s picture, and output straight to battery with 4 Awg wire...

I did some searching from internet about the mopar voltage regulators and seems to be quite common problem with stock and "old school" powerline but not in 3G hemi swaps. Lot of opinions that quality of voltage regulators nowadays is not as good as used to be. Some say that it is good practice to collect those "good old ones" from junkyard :) Also engine compartment heat got some thoughts.

Maybe I order good lot of those on trunk and see what happens.
