Thanks Phillip! What a great solution. Jim C suggested a solution using
old GP parts but I didnt have them - this is something I can pick up for
small $'s and I understand exactly how to use it from your description.
BTW, my GP system will work easily with your suggestion - I can unplug the
wiring harness that goes to the individual GPs from the relay - it'll be
easy to put the ammeter between the wire to each GP and the battery + side.
Thanks again!

BTW, I searched for a DMM that reads dc
current to 30a or so and no one had them. I'll order one though.
DMM can be hard to read the slope, or change over time.
The current draw starts high, then drops back a bit as the plug warms
up.
My favorite way to test them is with an old
add-a-gauge-under-the-dash-style ammeter. I had a +- 40A in my parts
box.
On a OM616 or OM617 with parallel plugs, I unplug the glow plugs from
the relay. This seperates the plugs - they now each have there own
wire. I then connect the ammeter between batter positive and each of
the glowplug contacts in the connector. It's quick and easy to see if
they all act the same.
I don't know how this method will adapt to a newer engine, but the
meter should work the same. I know Summit Racing sells an ammeter by
itself. I believe AutoZone does too.
