What concerns me is that all was normal until I removed and replaced all the wiring and K components... The first thing I noticed after getting it all back together was that the glow plug indicator did not light up. I may need to get a wiring diagram for the glow plug assembly. In the meantime I will go back and see which glow plug tested bad and see if it is the plug or wire. When the light does come on after the 30 sec delay, and the relay kicks on, I don't know if it's actually delivering voltage to the plugs, so I'll check that too.
