04 cranks - no start - code 19 but switch is ok

[rbar]

The reason for the code 19 is that the second set of contacts (smaller wires) in the ignition switch are in the path between the Starting Circuit Cut-Off Relay and the ECU. The normal state for that wire is either grounded (safe to start) or floating (start inhibited). When it is inhibited but the starter is run it throws a 19 code.

Thanks - if the bike keeps giving symptom-free starts I'll eventually trust it again. I need to check the function of the clutch switch - if it tests ok, then the cutoff relay is still suspect.

Brake cleaner is a good degreaser, but I'd consider the Pro Gold spray from Rat Shaq.

Caig Labs has another formulation that might even be better for the ignition switch contacts.
