Thanks gents.
The EI is a Pazon surefire. Prior to attaching both leads at the contact plate the electrics on the bike we're working as they should.
Now, the spare battery that I use to check electrical things is an old one that just holds enough if a charge to do what it needs to do, probably not an issue but I figured I would mention it.
Frank, I will recheck my ignition switch connections but they were working properly earlier and I have not changed them at all.
When I touch the - lead to the battery the horn sounds, thetthe light comes on and the plugs spark. Headlight switch and beam are not functioning.
Last week everything worked great, different battery and EI are the only two changes...
Appreciate the help guys.
Come to think of it, the taillight could be my brake switch, I'll check for shorts.
