Are you saying that you connected 2 wires to pin 1?  There normally 
should only be one wire to pin 1, and that is the AF line which should 
connect the other end direct to the + side of the electret element.  The 
other side of the electret element must connect to ground (pin 7 or pin 8).
Turn bias ON in the FP mic menu and likely with an electret, you can use 
the L setting.  In other words, the MIC SEL menu parameter should be 
FP.L bIAS.
