Gerald,
I think we agree that other owners have no idea what their alternator is outputting.
They only know what their batteries read, and those values are as high as 14.8 from what I've read. And that's about what mine read when I had my chassis batteries replaced and alternator rebuilt in April of 2014. Based on what I'd read, I felt this was normal voltage to see on the silverleaf. I now think that the alternator output at that time was about 15.8V, and I would not be surprised if other owners measure their output voltage that they would see something similar.
Since V=IR, and assuming resistance is a constant, a higher voltage will mean a higher amperage as they are directly proportional mathematically. My newly rebuilt alternator burned up during a 2 month trip across country.
Since being rebuilt the second time in 2 months (rebuild again in June 2014), the gents who repaired mine the 2nd did measure the output voltage (something not done typically because the rebuild is farmed out to someone else by a coach maintenance facility and therefore can not be tested on the vehicle by the rebuilder), and found it to be in the 15 to 15.8 range but only 14.2 on their bench test, I do know what mine was outputting, and also after they did the "fix" I know its now outputting 13.8 to 14.2.
So, I am still wondering if any owners will put a meter on theirs and see what the output post is reading. I wonder if theirs will show 15V or more, and if perhaps, this is the reason there has been so much talk of alternator rebuilds/replacements for these coaches. I do know that the other theory is that dry camping causes too much current to be generated by the alternator and thus burns out the alternator and that the fix for that was to run the generator in the morning or while driving to mitigate this issue. This was an actual precaution I used during my 2 month cross country trip, but it didn't save my alternator.
Thanks,
Mike
