How do you increase a voltage regulator from a 6v generator up to 8v to charge an 8v battery?

Answer

Without knowing what you have for a regulator, I can't say this will help. I did one last spring for a friend on his old antique boat. It is a 6v system which we changed to 8v (positive ground at that).

This regulator is on a generator, not alternator, probably same as you, basically a small metal box with a relay inside. The premis of this regulator is the spring tension is just so that at about 7.5 to 8 volts, it would trip and disconnect the generator. Simply adjust the tension so it trips at a higher voltage. You will need a very accurate volt meter, preferably digital. Also remember your target isn't actually 8 volts, 10 is probably close enough. 8.8 volts is static charge, I think 9.2 is operating charge so 9.6 or so would be peak voltage under charge (a 12V battery will show 14.4 sitting and about 15 while under charge)..

This worked great for us, doesn't show signs of boiling the battery but does keep it at peak..
