"when commanding the hotend to heat, I can read 12V at the hotend connector"
The hotend has the gnd switched, there is always 12v on the connector, one pin always has 12v, the other pin is 12v (via the hotend heater) or gnd depending on if the mosfet is on or off.
you must measure between the two hotend pins, not a common gnd.
