On a one wire mini alternator; in order to maintain a charge on the battery while motor is running; is it necessary to run a bigger pully on the crankshaft side & smaller on the alt side? currently im running 2 3/4" on both sides. Im continuing to have some charging issues. Battery is new as is alternator. Alternator is spinning at same speed as crank pulley. Am i missing somthing? Iv'e asked around however have got no solid answers wether this will or will not work. any opinions or knowledge would be appreciated.
