Is the M2 in dumb mode?
My m2-atx switches on the motherboard immediately when i give it unswitched juice, even if the J2 is disconnected from M2-ATX altogether. Does this in both the bench testing and in the car.
Is the m2-atx dead?
J1 is connected straight to the battery.
j2 is connected to the ACC wire from the OEM harness - verified that it's switched.
J3 is connected to GRND from the OEM harness.
for testing purposes, i've tried it without J2 - still turns on the motherboard.
then i tried putting the unswitched juice to J2 only - nothing
Yeah...check your j10 jumper setting. You may be in P0 mode (dumb mode) with no jumpers.

should i use the recommended (P1, i think) for it to work like a true controller? that is to turn the MB on only when IGN is present?
apparently it was I who was in the "dumb" mode.
hope to come out of it soon.
