Re: LS swap alternator issues
You might get/borrow a starter current meter, the type of meter slips over the cable, and see how much current is being converted.
Is alternator case hot to the touch? The higher the current demand, the hotter the case.
And, if two ground cables between engine and chassis/body, remove one of them - eliminates ground loop, more prevalent in AC circuits than DC circuits.
The battery is a parallel load in the electrical circuitry of car.
There should be a cable from alt BATT stud to distribution block, usually horn relay buss bar, then power lead to fusebox, and lead to battery junction block.
Yes, I read a cable from alt BATT stud to pos clamp, and may not be a bad idea, but, you might try a resistor in the line like OE design.
