I flip that only when the system locks up and the Opus cant shut it down or when leaving town for a while and dont want the carputer trickle-draining my battery.
maxxell, can you elaborate a bit on the exact configuration of the two switches (types of switch, location in the circuit, etc)
I thought the point of a relay is for the circuit to be open until the ignition is turned on, and then the circuit gets closed and sends the 12V signal to the computer PSU (provided the switch is also set to ON). If the ignition is turned on but the switch is turned OFF, the relay will still close the circuit to the computer, but the switch being set to OFF will keep the computer from powering up or drawing off the battery... no..?
