Not normal.  It sounds like you are powering the PiHat from the Pi and not vice versa.  While this is possible, its probably not the normal way.  Especially if  you are also powering the pixel strings through it.


I would double-check the power jumper settings on the PiHiat and then apply the input power to the Hat, not the Pi.

So I got around to checking my power connections and everything seems in order all jumpers are in place and as soon as I plug it in pi starts heating up

Good eye. Don't cross connect the AC ground and the DC ground. Depending on the manufacturer, they may be isolated by the power supply.

It shows up again next to the Green DC plug near the PiCap but doesn't appear to be connected in your picture.

Something is drawing too much current (you know that). You may need to send it back to Dave Pitts for refurb.

One of the capacitors could be bad or the wrong chips in the 8 pin sockets or a socketed chip in backwards.

I didn't read everything but the first thing that crosses my mind is are you sure that all the pins are lined up between the hat and the pi correctly.

Does Pi get hot when you plug it in separately.
