Series Fuses [RE-wrenches]

[Darryl Thayer]

Hi
The short Circuit was in the wireing between the
combiner and the Module, the actual short was between
the PV source circuit conductors.  The source of
current came from the inverter capasitor through the
fuse and negative return to the inverter.  I was in a
hurry and I should have climbed down and opened the DC
disconnect, but the old in a hurry get it done.
