HOW DO I CHECK THE STARTER RELAY

1999 Cadillac Deville

Electrical problem
1999 Cadillac Deville V8 Front Wheel Drive Automatic 80,000 miles

Cannot get the starter to engage. Have cleaned all terminals & replaced the battery.
When I turn the switch I get nothing. I have tried the second set of keys.

A relay is basically an electrically controlled switch. It uses an electrical signal to close a set of contacts in the relay. The contacts act as a switch allowing power in and back out of the relay. Using a test light, check for power and ground into the relay. If working properly, the switch should allow power in and out of the relay.
