The glow plug indicator light came on and went out as it was supposed to.  I suspect defective or burned out glow plugs. I know the procedure for checking the glow plugs and will do so this weekend.  Does the function of the light indicate that the relay is OK?

All it means is that that part of the relay is working, dash light and power to the plugs are two nearly independent functions of the relay:
