As you can probably see from the state of the wiring in the pictures it was an absolute mess. Every single piece of wire except the engine loom came out and was replaced. A while back the previous caretakers of the boat had used poor quality, non waterproof connectors and in one case had just shoved the important electronics ground wires onto the tacho post with no connector!
The battery was corroded (and undersized) so got the chop for a new Numax marine unit. However the engine was still sluggish to start. I later found out that Humber had fitted 16mm^2 cables for a 4m run when the manual says at least double that! New bigger cables fitted and all was well.
New LED nav lights and flood lights were fitted to the A frame and wired up to a custom made laser cut switch panel with a variety of carling switches. A Blue sea systems mini isolator switch was put in to replace the basic plastic key type originally installed.
