got kind of a sketchy reading on port #1--meter jumped around, kind of oscillated between 1.4 and 1.8. Nothing on the rest. Guess I'll try to jerry-rig some sort of wiring to the battery, just to get a good ground.

This seems like it's just as much work as replacing the glows--though I've never done that and the #5 plug looks like a tough one. What tools do you need to disconnect the wire and unscrew the glow plug itself? Haynes says "a suitable wrench". Any way to get more specific on that?
