##  You could also have loosened the mast clamps..and manually pointed the yagi 
at the rare one.
Plan B... get a bigger rotor for the job..or at least one that is more 
reliable.   Then again, if the interconnects
are unreliable, it’s a moot point.   I see some folks with m2 OR-2800 or 
similar have had 10 ft pigtails 
installed by the factory, instead of the usual 2 foot...... then do the cross 
connect on a terminal strip, inside a nema box.  
That would be the most reliable method.... but not the fastest...vs  quick 
disconnects.   A 100-200 ft pig tail would also work.

The_Man asked, "Why would anyone want to install quick disconnects?" 
Those were our reasons. 
But another important reason we omitted is: You don't always get to do a rotor 
replacement during ideal weather.
We wouldn't do this now, but back in the day, we once replaced a rotor in 15 
deg weather when some Rare_One 
we needed was going to be on that day. Also, the pile-up won't wait while one 
fiddles with 8 screws.....73, Don  N7EF

  FWIW, the quick disconnects available from Norm's Rotor have gold pins on
  both halves.
  Pricey, but don't expect any corrosion..

  After nearly 40 years of  using the old Ham IV   8-screw   terminal strips
  (never had a reliability problem)
  we are now converting to Norm's disconnects. As geriatrics become an issue,
  every extra minute on the tower hurts. Disconnecting and reconnecting the
  8-wires can consume 15-30 finger-fumbling vision-impaired minutes ---
  dealing with rusty screws and wires, slipping wire ends under those screws
  that really don't unscrew far enough to make the job easy, keeping the
  wires from oozing out from under the screws while tightening them,
  re-stripping and forming the wire ends if any broke during the
  disconnecting operation, finally making sure the connections are correct
  and tight,

  Maybe y'alll got a better way, but we always have done it with the rotor
  laying precariously *LOOSE* on its side, on the rotor shelf,  in order to
  get necessary easy access to the terminal strip,  Not something you want
  especially if some wasps seize the opportunity to attack.. A Rohn 25 rotor
  shelf is not very wide, makes a lousy workbench.  It is now a 10 second
  operation with the rotor solidly bolted in place.....

  ##  why not just install Sta-kon crimp connectors on each of the 8 x wires..
  then solder em after crimping. [ -SNIP- ]
