The subject is loss of power to three of 4 red power wires at the fuse box. A2resource says that for the MK3 92’ coraddo Y1-4 is main power at # 3 and ECU power at #4 but it shouldn’t matter on location orientation for the two larger AWG wires. I pulled the main and get 12V but when pulled and checked the other 3 red wires I got nothing. Should I be back probing these three while connected?! Because I should get 12V from the battery right?! Three red come off the + side of the battery! Symptoms include no Power to or very low power to just about everything in the car except installed gauges. No power to MAF, .025 to signal and constant while cranking, faded power to Injectors .023v, 9.9V to fuel pump etc ... battery fully charged at 12V.
