Re: Bigger Alternator?
True, the battery needs have not changed, its another parallel load - but I did not say to replace the fusible link to the battery - it still remains.
Since addition of fans, ease of wiring in power source for the physical location.
There may be the possibility of all circuits, if headlamp relay is added per lamp, and fans on at the same time - one fan per side, one headlamp per side, and recharge of battery, if OE design is kept in place, the #10 AWG running from alt BATT stud to buss bar could have as much as 80 amps or more, buss bar also supplies the rest of the OE vehicle harness, will do the job, but the heat given off due to wire internal resistance with large amount of current flowing may make it alittle hot. Install a bigger gauge wire making it 'cooler' and due to technology, better wire, read 'safer' as far as insulation, copper is copper.
Camaro could have A/C on with fan on high speed, all lights on, brake lights on, reverse lights on, hood, trunk, glovebox doors, a door opened, radio playing, maybe a power window, or all four being operated at the same time, auto trans in gear (lower alt RPM), and power steering being turned at the same time (lower alt RPM) - thereby lots of current flowing between alt BATT stud and buss bar. Did I leave any circuit out? Yes I did - horn.
As with the rest of the OE harnesses, I'm sure GM engineers did their homework in providing the proper gauge wire to load vs distance traveled and these circuits have not changed, as written here in this thread.
