I found my once squealing heater was not working at all and it's fuse
was blown.  It had a 25A fuse, which was supposed to be 30 according
to Bentley.  I put in a 30A and it is back running but I wanted to do
the Mullendore port lubrication.  I drilled the hole as specified and
got a light in there through the big air inlet opening but I do not
see the motor.  It is supposed to be straight back?  If I look
straight back I see a rectangular opening that looks like it might be
about 5" wide and 2" tall.  I looked all around as much as I could
and didn't see the end of the motor.  Help please.
