No brackets or anything else, typed it in the reply window, and it tells me invalid formatting. perhaps too long a response so here is the caveman shortened version
I have a K type thermocouple attached to my alternator's stator/casing with Arctic silver thermal epoxy..
It is a 50/120 chrysler externally regulated alternator, 50 amps at idle, 120Max, and it lives up to these amperage specs.
Maxed out at idle, or revving engine parked for more output, it will quickly climb to 200F.
Maxed out at 65mph and I can't get it over 140f
Danger zone for alternators is 220F+.
I do not know how much hotter the interior of alternator is.
Can your proposed depleted batteries and the circuit feeding them max out your alternator?
No idea.
My 1989 vehicle consumes 12.2 amps at 2K rpm just to run ignition/engine computer and fuel pump, not including field current to alternator.
I cannot get the full 120 amp output until almost 3K rpm, and I cruise at 65mph which is 1975rpm.
I can and do control the voltage my alternator is told to seek.
When my battery was newer 2/3 more amps would flow into it at 14.7v compared to 13.7.
now at 5+ years old and 1000+ deep cycles that is closer to 1/2.
