The way I was taught to check glow plugs was to take an amperage meter and attach one side to positive battery post and other side to glow plug terminal & "briefly" check amperage draw.
And The Reason The Glow Plugs Burned Out !

you can check the resistance of the glow plug with digital multimeter set to read OHM's. should not read OL or open. disconnect the wire from glow plug. some glow plugs have the resistance it should read stamped on them.

Well, everything is 100% now. New glow plugs and new relay switch for them. Glad I got everything straightened out before winter gets here. Glow plugs were about $135 for the 3, relay was $89. Good to go now .

Good thread glad it worked out for you.
In the morning I plan to install a new alternator on my diesel pickup, now I am concerned I may have overlooked the glowplug controller as the real problem.

I have a mini ex that is just the oposite of what you describe. It won't let the glow plugs come on or shuts off to soon. I allways wanted to bypass the relay and just have a manual glow plug button but there is to much involved on this machine.

Put a current clamp on the new alternator lead this morning and it was loaded down with a 89 to 90 amp charge rate for a full minute or so then started tapering off slowly to about 35 amps. I know if had to recover from using the starter for a few seconds but it seems the glow plugs may have been on longer than I expected, don't know for sure. At any rate within a couple of minutes my charging voltage was just over 14 volts. Guess I need to pay attention to the glow plug controller in case it starts to crap out on me.
