So, I decided it was time to tackle the motor's wiring loom. It was in a real state.
This first image is the loom removed, wires labeled and laid out on a inboard (so that I can keep track of it all).
This is what she looked like after I toll all the electrical tape, heat shrink and heck knows what other stuff.
All the wires that were under the electrical tape were coated in this revolting sticky goo. I guess its a buildup of fuel, cleaners, WD40, etc over it's life.
These are the wires that were not wrapped. Pretty rotten!
