re: 91 Spider Airbag Light

Robert,

I also have a '91 Spider with the same problems.  

As far as the airbag light goes, if there is a fault 
detected in your circuit the light will blink for several 
minutes then turn ON.  If the diagnostics were completed 
and you went thru the 3 sec power off, 3 sec on, disconnect 
and off, then after at least a ten second wait before 
turning the ignition on, the light should go on for several 
seconds then go off.  If it immediately starts to blink 
when turning the ignition on then the reset sequence did 
not work.  (that's where mine is now)  If it goes on for 
several seconds then starts to blink, a fault still exists 
in the system.  Either way, if you have a fault in the 
system it is normal for the light to blink for a few 
minutes then turn on.  If the reset worked, its supposed to 
turn on for several seconds (not blink) then turn off.
I believe I understand the system well enough, but I am 
obviously missing something 'cause I can't get mine to 
reset.  I even tried a variation of the sequence that was 
suggested to me by Pasquale of Ferrari of Seattle.   If 
anyone has any suggestions, please post them.  I too would 
appreciate the help.

Your warning bell was an easy one.  It's the same circuit 
that detects door open with the key in.  Check the lower 
switch in the driver's side door jam.  Mine had rotated 
slightly and was contacting intermitently causing the same 
symptoms as yours.  I just rotated mine back and tightened 
the screw, no more problems.

Good luck,
Fred
91 Spider
