Can you check voltage at each glow plug terminal while glowing?
Can you attach an ammeter to the big red wire into the relay? You should see 40-60 amps while glowing.
Feed +12V to the black wire in the small relay connector (disconnected from the relay!) and see if the glow light comes on.

When he was talking about the fusible link, I didn't know what that was, but I see what you mean now.
We tested when the relay kicked in, that each glow plug (measuring from inside the 5 holes on the pin switch in the relay box area) and we got something like 12.69 or 13.69 or something, to each plug, straight across.
I'll try the big red wire in a few minutes, see what I get. I'm guessing I have to hook the black wire of my tester to the negative battery, and the red to the red wire on the relay?
I don't know how to feed 12v into the black wire.
