I recently acquired a Hehr Aqualine 10-82 regulator
. The manual for the unit says the following:
is a "high side" device intended. for use with "P" type alternators only. It cannot be used with alternators which are regulated through the ground side of the field winding.
I understand a "P" type alternator
is one which is set up for external regulation. But I don't understand the meaning of "high side" device. I also don't understand the 2nd line, I thought alternators were regulated by varying the voltage on the field. Can anyone enlighten me as to what this actually means?
I was thinking of using this with a Prestolite/Leece-Neville 90 amp alternator
that has been re-wired for external regulation by grounding one side of the field to the case and running the other field lead outside the case to be connected to the regulator. Prestolite makes a kit to do this. This regulator can control the amp output and I going to set it at 50 max figuring that would easily re-charge our tiny 230 amp house bank and not kill the alternator. Will this alternator will work with the regulator?
