Post No start, glowplug relay buzzing

Yesterday after changing oil, oil filter, and fuel filter, my 1985 TD wagon would not start. When the ignition was turned on, a loud buzzing noise emanated from the glow plug relay box. The starter would not engage when twisting the key. This seemed to me to be totally unrelated to the maintenance I performed. There seems to be enough fuel in the system to not be an issue. I see no faulty connections. I charged the battery overnight with a 10amp charger; no change in the issue this morning.
Do I need a new (or junk yard) glow plug relay box?
My thanks to all you avid benz trouble shooters for issues I was able to solve from previous posts. The only thing I found on this issue ended up being a undercharged battery.
