Was the molex plugged into the H3 during the measurement?

Re: Wiring issue
Lets go a bit further, check the soldering on each pin of the fuse holder. The one nearest the edge of the board is directed linked to the red molex cable. It should have a 12V there. Also check the soldering quality of the molex connector.

Re: Wiring issue
visually, all soldering is ok. on coonection pin solder point for red wire to control module voltage drops to ca 8.8V. on fuses, measured at solder points from bottom side of circuit board i've got 0.25V both sides.

Re: Wiring issue
Unplug all harness except the molex.
Can you measure the voltage between the red wire and the 5A fuse, either side.

Re: Wiring issue
I would take the circuit board out of the car and do it in front of the computer with a meter. you don't need to plug it into the molex.
