I won't pretend to be an electrician - I am very much a DIY enthusiast when it comes to wiring! I like to try my hand at everything though, and having re-wired two bikes in the past, I have a rough idea of what I'm doing.
You know what they say though, Proper Planning and Preparation Prevents Poor Performance (or whatever it is). Anyway, the point being that I'm designing my circuit before I start splicing wires and connecting things up. For me, that process starts on paper! I've come up with a plan, so now I'm going to start collecting some parts, ready to test the circuit.
Very exciting stuff - especially since I'm well and truly in "Dakar" following mode at the moment! Can't wait to get a roadbook together and go out for the maiden navigation ride.
