first of all we must know more of the initial task, as it is its like saying is an apple better than an orange
a dc charging system in an older type motor car works just fine ie the system recharges the batt after eng start so the batts ready for the next start ----- got that?
there is no sutch thing as an ac charging system, you can have an alternator,like a modern type of motor car where the pwrs made in a alternator (ac) then turned into dc (lots of miracles) then passed to batt
--does that make sense??
i have a bunch of old motorbikes that have dc systems and they all work just fine, you have to remember they are products of their time and if you do not expect too much you will not be dissapointed.
scuuse the spling its the whisk you know!!
