"That might work if you don't burn up your alternator"
No no no No No NO NO!
Yet more hypothesis sans experience...
The quiescent load of say a Lincoln Navigator, alternator at night, using A/C and headlamps in 72-77 amperes. Go to Phoenix on the 4th of July. WOW! Look at all those tow trucks snatching burned alternators off the freeways at 8:00PM on a refreshing 109F night.
This nonsense is like squashing the head of a Hydra. It pops up, STOMP. Over there. Stomp. Then there, STOMP.
GM had a BAD PROBLEM in the early 80's with the 12SI DELCO and that SMART flat plastic and aluminum TURBINE fan. Get this -
The stupidity burned up 66 amp motorhome stators. That stator used with a full-fill rotor bobbin created the 7278 Lester 78-amp version of the 12 SI. Motorhome manufacturers saved 11 dollars per chassis by not opting for the 78 amp version spec in the chassis. Yes, 66 amp motorhome alternators. The practice was universal.
So what did Delco do? When the CS130 alternator was designed to replace the 12SI, A STANDARD METAL BLADE FAN was reintroduced along with a plastic SRE TURBINE FAN. The stupidity continued. Later model rotors used a steel blade fan on the slip ring end. Let's not talk about Delco's insanity of leaving the A6000X slip ring end bearing open to the engine compartment, and catastrophic alternator failure.
OEM alternators use minimum standards rectifiers (anything rated above 3 amperes is not referred to as a diode. Lose a rectifier, burn up the stator. This is where the BURNED UP horsepucky originated. A "rebuilt" alternator uses even WORSE grade rectifiers.
My MAKE YOUR OWN REMOTE RECTIFIER comments went unheeded it seems. Pity. It converts a suffering motorhome alternator into one that laughs at full load 24/7/365 at 120F ambient temperature.
