M2-ATX - Powers up PC when ignition is off!
This is my first post!
I've built my system up and have had it working fine on the bench and have started planning the installation in my car.
I'm using an M2-ATX supply to power up the system and monitor - the monitor is set up to auto start when it gets power from the supply.
I have taken power straight from the ISO block in the wiring loom (although I've just read a post that I should really wire it straight to the battery) and something very strange is hapening. The PC powers up when the ignition is OFF and hibernates when you switch the ignition ON - Has anyone had any experience of this?
After testing with my meter the ACC wire seems to be giving off a zero voltage with the ignition ON and 5V with the ignition off.
If I simulate the ignition trigger by manually connecting and disconnecting the white wire on my loom the PC starts up and goes into hibrenation as it should.
Any help to get me on to the right tracks would be appreciated
