[Shotimes] Low voltage light

[Carl Prochilo]

I like this theory the best ('cause I don't have to do anything).

I would assume that there is extra capacity in the diode bridge which is
why this becomes okay.  The broken diode will eventually become high
resistance and the current flows through the remaining diodes.  The light
has stopped coming on of late, but I will keep an eye on it.  Worst case
is I need a new alternator.  I don't have time or patience to rebuild it
myself.
