This is very well possible, just as I said, there is no connection
between the battery and the regulator.
The only odd thing here is that there is no voltage on the output of the
regulator. If the regulator was wired according to the books, then the
RBC connectors are tied together, and connected to the capacitor which
should be hard wired to the regulator. In this case, with a blown fuse,
you would expect a correct (but useless) 13.7 Volts at the B+ tab, and a
12 Volt at the battery. But Jeff doesn't see a voltage on the output,
indicating that there is more of a problem than just a blown fuse. I
suspect that the capacitor and/or C connector is behind the fuse, and
the regulator has subsequently been destroyed.
I think we will hear some more soon.
