Is there only one alternator (like the 400) or are two driving the meter?
Where does the gauge info come from, or does it avg. the outputs of the two? If an alt. becomes faulty, does the gauge have two lights (one for ea.) that would display which one is faulty, or is it process of elim.?
Pretty sure mine was running on only one of the alternators for quite a while. When the working one crapped out, that's when the battery died, and I discovered both had to be rebuilt.
