[QUOTE="Queensland Ken, post: 1204913, member: 4399"] Hate those type of coincidences. Why did the recall fail ? I'd go through the process of informing Yamaha and the appropriate authorities, ask your dealer the questions and document everything !!! Will the dealer inform Yamaha of the recall failure ? The recall involved adding a bridging connector to the S4 neutral connector and taking a parallel wire back to the battery, hence reducing the neutral current. However from what the dealer described to you, it is the classic fault on the S4 connector. Just because the recall was done, it doesn't mean that one of the other 5 12 volt high current neutral bridging connectors or wiring is crook, or high resistance pin/connector on a transducer / sensor neutral connector blocks, 2 of them. Also remember that there has been high resistance and burnt wires on the front cowling connector block #3. Such a fault will exhibit similar symptoms to a classic S4 fault, as it contains the "daisy chained" neutral wire from neutral connectors 6,7&8. The neutrals from the LHS switch block loom connect to the bike's loom in front of the motor under the tank. A high resistance on that connector block may effect functions of that switch block. If the diagnostic functions of the YCC-S are fine, you would have to check out all the "spiders" and the connector blocks associated with the auto clutch. [/QUOTE]
