As soon as I turn the 12-volt power supply on, the P3 powers up even though the K3 is not on. When I hit POWER on the K3 to power down the K3, the P3 stays on. To power down the P3, I have to turn the 12-volt power supply off.

Lower right corner of K3 RF Board schematic, Sht. 3 of 4.

J10 = 12V In, J11 = 12V Out.
