? But the PTC's are feed from pulses from the IGBT(maybe more than one),
so no direct connection from input high voltage. One would have to open
up the core and remove the circuit board that feeds the PTC's. Which may
mean un-soldering, or breaking a spot weld. to test the core would require
either building your own (maybe arduino) device to send control signals,
or maybe find a way of setting up the cars A/C auto amp to send the signals.
Can the core be opened up easily? I have seen a cut away showing the PTC's,
but not the circuit board.
