Check Engine Light?
Quick question for my 82 cadillac coupe deville with a ht4100. when i turn the key to the ignition all the lights come on besides my service engine light. The light does come on when i crank the car over and all the rest of them turn off and stay off including the service engine light once the vehicle is started. Is this the way its supposed to be because the smog guy is telling me that the service engine light needs to come on when i turn the key to the on position. He is failing my car for this reason but all the numbers are legit with the emissions test.
