Re: 1995 Buick Riviera Supercharged - No power to under hood light

Basically, I think it is a mercury switch......just disconnecting it, eliminates it.....

The yellow wire should have 12 volts, I think with the headlight switch in the headlight or park position....the black wire should be a good ground....

Remember on this vehicle, it could take up to 10 minutes for all modules to go to sleep when doing a draw test, correctly.....
