yep, try jumping past the relay, like larry said ...positive from battery directly to the main starter wire
as for the wiring, heres how i look at diagrams..............
look at the component suspected, (switch, relay, cdi box, coil, fuse, starter, ect)
then follow each color wire, one at a time, to the other end
now look on the bike at those 2 components and find that one wire, pull and continuity test that one wire, or check for power, if it isnt broken, move to the next color wire,
there is no need to follow each wire thru the harness itself
the diagram shows you were it goes
if you have to, print the diagram and in your own words, label each component on it, and it's location on the bike when you find it
then start ohming out the wires or checking for power, one color at a time
