Hot shoe pins (contacts) voltage?

Does anyone know the hot shoe pins (contacts) voltage on a K5 so I can check it when HOT (power on).

You probably won't be able to detect anything with a voltage meter. The metal shoe is ground, the center pin is an open ground that closes to trigger the flash. The two pins to the rear receive the READY and MODE signals from the flash, so there is no voltage from the camera. The DIGITAL pin (closest to the front of the camera, upper right corner) is used for digital communication between the flash and camera. You might see something with an oscilloscope, but it isn't a continuous voltage, and there's probably nothing to see unless a flash is present.
