The single core field wire connects to the terminal under the fuse, the other side of the fuse is connected via the strip on the underside to F2. The second strip goes from where the blue D wire is connected now (also the top of the home made looking resistor) to terminal F1, the D terminal on the resistor doesn't have anything connected to it just now.
Thanks Bob, I will take a look.
