What is the terminal identified as "cut-out". If you apply voltage will the regulator shut off?
I own a Prestolite AS128e alternator, and i need to be able to turn off the alternator with the alternator field switch, that I have installed.
How could i do?
Should I install the 100-265S cover and then an external regulator?
Any help would be appreciated, thanks.
I have a pair of alternators marked ANE 5204 on 1973 Chrysler Marine M440 engines. I want to replace them with alternators with internal voltage regulators.
What is the correct Alternator to use?

Dear Sears, on a restored Gardner engine is a second alternator typ BRG 3078 installed. This alternator is only for the main batteries used, not for the starter and the starter batterie. Please, could you send me a detailed cable/ wiring plan per e-mail? What kind of regulator I have to take? Thank you very much Michael Schilling - firstname.lastname@example.org
Would like to obtain general info for on board testing.
2 engines, after 10 minutes @ idle show 27.1 volts and
27.5 volts, (inexpensive sears vom). Is this about where I should be ? Did not test @ higher rpm this run.
I have this altenator installed on a 2006 Bluebird with a C7 Cat. It was just rebuilt they took off my marking for the wiring does anyone have the diagram.

Which LN 12v alt over 100amps IS UL and USCG approved for marine use?
and can you convert one to an external smart regulator?
Where will I find the output graph to confirm my pulley sizes?
I assume they also have a tach terminal which I will need
