I cant understand why so many are pre-occupied in using a test meter, you are trying to see if the GP gets a proper glow pattern, you need to see it going red. You also need to make sure the GP hole is clean & doesnt require reaming. No test meter can determine this. Its time to get your fingers dirty!!

perhaps we should add to the service interval a series of glow plug service to the valve adjustment plan.
at 15K, the GP's should be pulled, and the holes reamed. also, the plugs themselves should have power applied and verify the TIP gets hot bright orange at a minimum.
