Voltage Regulator
 

Regarding 6 V positive ground system, does the voltage regulator also need to be 6 V positive ground or does it not matter?

Yes

No, the regulator is not polarised, the generator needs to be polarised to operate on positive ground. The regulator is primarily regulating the current supplied to the battery and cuts out at a particular voltage threshold regardless of polarity. Do a google search on polarising your generator. Hope this helps :)

Although the regulator will work either way, depending on how the generator is polarised, negative grounded regulators have the flat contact point on the regulator armature. On positive grounded regulators the flat contact point is in the upper contact bracket. (The other point is rounded or crowned.) Using the wrong polarity regulator will cause the points to pit badly and give very short life. Regulators designed for positive grounded systems have copper plated current and voltage regulator armatures while regulators for negative grounded systems have cadmium plated armature
