Yes - you can test to see if the glow plugs are getting 12v., but that doesn't mean they're getting hot. I like the suggestion to use a battery charger with an ammeter to read the current draw, or buy a $19.95 30-0-30 ammeter from a McParts house, connect a couple of 14 - 12 gauge wires, and put it between the wire and the glow plug - read the current in place.
