Depends where you're measuring the system voltage -- but that's an awful
high drop, even right at the blower.  Trace the supply lines back until you
find where that drop is occurring.  Might save yourself a fire or melted
wiring.

Poor ground would get warm/hot, must fix.  This does *NOT* however account
for the blower drawing down the system.  Sparking is normal.  If the motor
were drawing too much the whole wire would be warm (and the fuse would blow
-- you did take off the tinfoil, right?).

Probably not, but you can measure -- the motor draws just about twelve amps
at high speed.
