This next test may seem weird but set your meter to DC volts, red lead to a test point on fuse 24 black lead to pin 10 c270e violet/orange. You are looking for 0 volts after the waiting period. The instrument cluster is acting as a switch providing a path to ground for the relay. When the time is up the path opens and kills power to the circuits. We want to see if it has failed in the "closed position". If it has a ground will always be present.
