[Shotimes] Cooling Fan Problem - How to troubleshoot?

[Dave Ulring]

Jason, All,

I have finally gotten around to doing some testing on
my SHO.  I have driven it a little on short trips
making sure not to over heat.  

I unplugged the fan and started the car.  No voltage. 
I turned on the AC MAX and got voltage.  I plugged it
back in and the fan started working.  I turned the AC
off and the fan turned off.  Normal behavior at this
point.  I turned the AC back on to see if it would
spin up again and nothing.  Tried several more times,
nothing.

A KOEO test only produces a 111 and 542.  I will have
to look into the secondary fuel pump circuit later,
but for now, could that be related to normal fan
operation?  

A KOER test does not spin up the fan and only produces
a 111 when I turn the steering, brake, and goose
properly.

Ideas?

Thanks,

Dave
