The shop did the glow plug replacement the first time. When we found the burnt glow plug caused the harness fire they did the repair work under warrantee. So I wasn't out any pocket money, just my labor to diagnose and repair last night. But now at least I know that circuit inside out. Lol

 

One good thing out of this is I now have the Ford glow plugs............

I starts now like a gas burner.
