right, the glow plugs and starter do not control each other. Check to see if the starter is really drawing any current.

hope this link shows up, I've never tried to post one : www.jcwhitney.com/autoparts/ProductDisplay/s-10101/p-469/c-10101 this is similar to an item I got from jc whitney about 20 years ago. Mine works great. I don't expect miracles for accuracy, but it sure is handy. All you have to do is place it next to the wire and the current reads out. No disconnecting of wire is necessary!
