Does any knowledgeable gentleman know if the pinz alternator has a negative or positive field? I have a test result, but want a second opinion.
Thanks greatly

Re: Alternator field, pos or neg
Some will scoff, but I bought an aftermarket regulator. Got tired of fussing with batteries, and when my regulator started kicking out 48v (lucky my volt meters were there!) thought I'd try a three-stage regulator to keep those batteries tip-top and long term.
Just have to figure out how to hook the darn thing up now.

Re: Alternator field, pos or neg
I'm not sure that I understand your question; the rotor is powered by DC, the polarity does not matter (and it does not change, either) but the strength changes as the regulator commands. I don't know if it is grounded and the regulator adjusts the positive current or if it is held to +24V and the regulator pulls the other end to ground (this may be your question).Does any knowledgeable gentleman know if the pinz alternator has a negative or positive field? I have a test result, but want a second opinion.

The alternator field is positive! If anyone was holding their breath.

Re: Alternator field, pos or neg
Sorry Jim, didnt see your reply at first! Yes, that was my question. I didn't realize there were more than one kind, but the installation guide warned of releasing smoke if not setup for the proper field polarity.Jimm391730 wrote:I don't know if it is grounded and the regulator adjusts the positive current or if it is held to +24V and the regulator pulls the other end to ground (this may be your question).Does any knowledgeable gentleman know if the pinz alternator has a negative or positive field?

Quick comment to an older thread. On older Harley Davidsons and many other generator charging systems it was necessary to "Flash the Field" when replacing charging system components. This was done to ensure the proper polarity of the generator.

This applied to old style generator systems, but not to modern alternators in a Pinz....many other generator charging systems it was necessary to "Flash the Field" when replacing charging system components.

My lack of electrical understanding always has me trying to better understand so: http://faqs.alternatorparts.com/2012/08 ... ators.html.

Yup. My point exactly. Sometimes old ways on old parts make their way into the modern world.Jimm391730 wrote:This applied to old style generator systems, but not to modern alternators in a Pinz....many other generator charging systems it was necessary to "Flash the Field" when replacing charging system components.
