Using CF's flowchart, I may have detected a bad ignition switch or wire. The voltage at pin 86 at the fuel pump relay is only 5.6 v. Am I correct in assuming it should be more like 12? (Incidentally, the voltage at the starter button was 4.6.)
Background: Push starter and nothing happens. Dash lights light as they should. I cleaned both major grounds, cleaned starter, have 12v at starter relay. Don't hear fuel pump sound. Occasionally hear click from what appears to be starter relay.
Bike ran fine, intermittently I would turn the key on and get no dash lights or dim ones and no start. Turn key, get bright dash lights and started instantly. Oh yeah, it has a new battery.
