Troubleshooting
a) Motherboard is not turning ON: Check input cables. Make sure you have a
a well tighten wire harness. Measure the un-switched pin (red). You should see
12V (car on) or 0V (car off). NOTE: In P1, P2, P3 modes if V(In) is < 12V, the
M3-ATX-HV will not start.
b) Motherboard is not turning ON (cont): Ensure total system power
consumption does not exceed the M3-ATX-HV specifications.
c) Motherboard is not turning ON (cont). Make sure that the ON/OFF wire
harness from the M3-ATX-HV is connected to the ON/OFF switch of your M/B.
