electrical prob.

Been at this all day, no joy. But
When I apply 12 volts to the brown terminal wire that is in the headlight switch plug, I get 2 volts at both my coil wire and the big pink wire so the leak has to be down that Brown wire but where has got me completely stymied...I look at the diagram and it just disappears in the fuse block.
Ps for giggles replaced ignition switch without change. Stl 2 volts

From your ignition switch Brown white trace is field feed @ alternater. Feeds into the warning lamp. This would explain your voltage drop w/ feeding it with 12v.
see figure 2 and 4
From your headlamp switch, brown wire feeds the parking lamp circuit. Brown and white trace is the ignition feed from the fuse panel and is fed by bat circuit on the ignition switch.

It would be better to feed your system with the large pink ign circuit. See circuit that feeds your original coil +. see figure 2A
