Voltage regulator upgrade? Keep frying voltage regulators with swap
I'm not sure this makes perfect sense. IF he has one with integral regulator, why would it not have the proper regulator already installed?
Additionally, the Chrysler "big frame" 100+ amp alternators of the late 70's used the same regulator as the small frame 30+ -- 60+ amp units
Here's what I think:
1....Something could be mis--wired
2....The alternator field could have PARTIAL SHORT which does happen and causes excessive field current..........so measure it. Hook a multimeter in series (ammeter / current) and slowly turn the rotor so the brushes "average out"
3....And there's the everlasting problem of Chineseo quality. Where are you getting regulators? Maybe you should try the junkyard, as in "old stock"
My beater piece of you-know-what old FJ-40 ran a big frame Mopar alternator for most of it's "life" AKA dual batteries and Warn 8K "wench." The regulator that I put on there in about 1975 or so was a used Mopar, and it was STILL ON THERE when I junked it a few years ago
