No additional tests are required for the resistance of the glow plugs.
I'd pursue the fuse as the culprit and, if not, the relay is the next choice.

Brian,
I agree that checks the relay circuit (go battery to the relay fuse to check the relay circuit alone), but, if the relay checks out ok, how does this test identify which plug is bad? If you recall the original problem was an apparent issue with one or two plugs that went awry when the "mechanic" got involved. I guess it is feasible the relay is now bad, but I was still back in the phase of the problem eliminating the plugs as the issue before expanding the scope or jumping to something else.
And, I have actually left the plug connecting the glow plugs to the relay unplugged/not fully engaged before, twice, in fact. That can be checked visually or by just pulling it off and making sure everything is aligned, and then pushing the plug back into the sockets.
Jim
