They should be near the same. The regulator limits the amount of amps that flows from the generator. A gen. would distrucked itsself if it kept going faster & faster. The voltage is an important part also. It is easy to test. It should not go over about 14.5 volts. 14 is preferred. If the voltage is too high you will damage the battery & lights & acessories. One of the advantages of an alternator is it wont put out more then its rated output of amps no mater how fast you turn it. The voltage still has to be regulated like the gen.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
