[QUOTE="Bokerfork, post: 1313941, member: 14213"] Maybe, to a certain degree. But every load you add to the system, i.e. aux lighting, heated gear etc.[B] IS[/B] running off the battery. And now the job of the alternator is to keep the battery at a net loss of zero amps. AMPS not VOLTAGE The voltage from the alternator is higher, yes, and is, or at least, should be, constant. This is known as the "float" voltage. It is the alternator Amperage which determines the battery "charge". No load on the battery and the voltage remains the same, i.e. at the "float" level. It is the amperage which will drop to the level demanded by the existing load, be that the factory load or the factory load plus any accessories you've added. None of this really matters since the question is 30 amp harness vs. 50 amp harness. Given the fact that the alternator likely puts out far less than either of those figures I supect the question and answers are moot. [/QUOTE]
