Query: Some eccentricities

Inverter works, but documentation doesn't mention that the power led has 2 states, red and green. Plug into Civic lighter plug and turn on ignition and you get a red led, but NO A/C POWER OUT. You need to get the green LED for it to work, which apparently on my Civic requires that you turn on the ignition first, then plug in the Cobra.
