Connect the alligator clip of the TL to a known 12-volt source or use the positive pole of the battery. With the TL connected to a 12-volt source, place the tip of the TL to any known good ground for test. Then test terminal #85. It should not lit up (NORMAL). If it does lit up, you got a PROBLEM.

Rick,
There were mistakes (typo) in the last 2 sentences above (post #9). It should read as:
"It should lit up (NORMAL). If it does not lit up, you got a problem"
My wife was calling me for dinner and quickly posted it. I had it backward. My mistake.
To recap it, the reason the FP is running with the ignition switch @ ON position could be caused by:
a). A defective FP relay.
b). Terminal #85 is not grounded.
Your test has shown that terminal #85 is not grounded. This is the problem. It should be grounded. The culprit could be one of the following:
a). Terminal #85 has a loose or open connection to the AFS (driver-side) pin or terminal. A continuity test has to be done.
b). The AFS switch is misaligned and not getting a good contact with the sensor plate.
c). The connection from the passenger side of the AFS terminal (plug/connector) going to D- (alternator) is loose or open.
Any of the above condition will cause terminal #85 to loose ground contact.
