Tow Vehicle Battery and Alternator
My trucks alternator is rated at 150 amps. Its starting battery is your typical 600 CCA AC Delco variety. My goal is to increase charging capability through the 7 pin pigtail connector near the hi...

The original wiring from alternator to starting battery and its fuse was likely not intended to carry an additional 40 amps.
Can it, should it, will it be fine? Depends on the gauge.
SO I usually recommend the alternator (+) stud when it is easily accessible and one can stack another ring terminal on it. There is an advantage in that if one takes power from starter battery, there should be an additional fuse added near battery + terminal, but if one takes it from the alternator there is already a OEM fuse between alternator and starter battery and no additional fuse is needed, unless perhaps the product instructions demand it.
That winch style connector on that first link I posted, is a good one, but is not moisture proof unless one makes it so by filling gaps where wires enter housing, and filling the contact area with dielectric grease.
Anderson makes those types of connectors in the SB style, not the smaller powerpole 15/30/45 amp flavors that are limited to 10awg.

perhap$, a better option:

Proper wire termination is always important for long term reliable low resistance connections, so factor that into your connector choices
