>>>Interesting.   The theory is that the spinning fans act like 
mini-alternators and feed 12V back through the system after the key is switched off, 
electrically funding the ignition system and allowing for weak sparks to keep 
the engine sputtering until they spin down.   The normal fix is to just 
install diodes in the ground wires and ground the fans locally to the body.

>>>There is an idiot light in the speedo for just that purpose.   It's a 
simple matter to string a single wire from the FAN bulb forward to the output 
of the #2 fan relay.   When your second fan kicks on, the light illuminates. 
  It's a beautiful thing.

Apparently Ford chose to disable this feature because customers viewed it 
as a warning light rather than a happy, everything-is-working-as-planned 
light.

Customers are idiots, apparently. :>)
