i have been restoring my 65 mustang coupe that has a 200 6 cylinder engine in it, and i have encountered a charging problem. the battery will charge sometimes and then it will stop. if i fool with the voltage regulator it will start charging, but only returns the previous problem very quickly. i'm thinking of going with a mr. amp 130 amp one-wire alternator since i'll be installing a decent sound system in the near future. is this a good idea?
