I have a question about alternator wiring. I have a smaller version of the 140 amp alt that came on the z28. It is still a CS style alternator but its smaller in dimensioins to fit where I need it to. The harness connections are the same as the Z28 alternator. I want to use the factory idiot light on the dash i
in the Malibu to give me heads up if the alternator stops charging.
Here is the alternator I have >

Look at the attached pic and you'll see how I have it wired up. Is this correct to light the idiot light if the alt fails to put out?
Should the gen light come on with key on engine off, or only light up with engine running and alternator failure?
