[QUOTE="Papermaker85, post: 8559844, member: 572595"] you see the decrease in voltage because the alternator cannot instantaneously saturate the permanent magnets to produce the current o there is a lag that cause the voltage to drop so it can saturate it. its called ripple current. the current increases in order to deliver the power. you need a Capacitor to help smooth the ripple.. those older caps aren't very great. with 3kw you could get away with 5 300F caps series..
