Had my HID from DDM for couple of years. Decided to install the relays today. Have the dual relays from DDM. Installed them today, 2 ground wires going to chassis one to + post. Soon as I plug in the power relay to ballast there a loud click from Relay (assuming that's normal) and the very light buzzing sound from the ballast. Headlights don't turn on. Thought maybe the wiring on the tray was reversed, flipped the plug ( no buzzing and no click from relay) and no lights.

Any ideas? Bad relays? Is there a way to test relays with a multimeter?
