I wanted to make sure the new 12v regulator would mount in the same location as the 6v unit so I went to the local NAPA. I asked for a regulator for a 1955-59 Chevy truck. They told me there were 5 choices, matched to the generator output. Anywhere from 30-50 amps. I put a new front bearing and brushes in my generator and didn't get any questions about different models at that time and there are no tags left on the generator so I do not know the output.
I guessed the 30 amp model was what I wanted. Napa has two voltage regulators for the 30 amp generator. Both made by Echlin and both made in the USA. One is 3 times more than the other (less than $30 vs. almost $90). The parts man tells me the internals are different.
To me the voltage regulator is just a black box. I can polorize a generator and I have freed up stuck points but that was decades ago. Not knowing anything about the differences I went with the more expensive unit. Am I wasting money? I can always exchange it but I am willing to pay for the more expensive unit if it is more reliable and better made. Any opinions about this are much appreciated.
