I guessed he is trying to read codes from the Aldl. His profile says it's an 80, and I didn't think they had Aldl connectors, so I have no clue.

I think I know what he was trying to do since he was using a test light. But he should have checked between terminal A and ground. this would indicate the condition of the check engine lamp. (if light glows the lamp is OK.)

my gm manual says connect d and e with screwdriver???????to get check engine light. thanks, bill

yes d and e to read codes. Grounding a will cause the check engine light to light up with the ignition on (which it should anyway). But can be useful for working out if you have a bad lamp or a bad ecm.
