    I think there is two different NSN's, with the same part number. In any case, a non problem.

    Thanks again. I found it in the Technical Manual on a conversion update to circuit breaker. Now when I go back out I know where this is to look. I can also make sure the 60HZ is selected. I also see that the ammeter uses a real shunt. So I can double check the panel meter on the front for accuracy. It was in the green briefly one day last week and when I put voltmeter on cranking batteries I had 28.4V But in a few seconds the panel meter zeroed out again.
