    Yamaha vstar 650

    Trying to sort my bike out. I went to start it and as soon as I pushed the starter motor the bike went dead just a small turn of the starter. No lights no nothing really strange. Checked fuses, ok, any idea where to look? The lights where good and bright before it happened. Battery about year and half old.

    I would remove the fuses to check them if not doen already. They may look good but on close inspection they show to be blown. Also a battery can quit at any time.

    Things to check are tightness and cleanliness of both cables. Multimeter across the terminals should read 12.5 vdc at rest rising to 13.5 vdc running then rising to 14.5 vdc at around 5k rpms. Anything lower than 10 vdc while cranking indicates a dead battery.

    Next I would be checking the starting circuit for a short. Work back from the start button. Are the lights and fuel pump still working...you should hear the pump prime...also most bikes do a sweep of the instruments before the pump primes...is this still happening? Check all connectors near the battery and ecu....wiggle the wiring while holding the start button to see if its a bad connection.

    A long shot would be the safety cut outs on the side stand and clutch....you can disconnect these and jump the harness connector. Do one at a time and makes certain the bike is in neutral whie you do it.


    Good luck

    Don't make this harder than it IS.

    Most likely cause: Loose or corroded battery cables......at either end.
    Next most likely: Failed battery.

    A multi-meter is an invaluable tool for electrical troubles.
    Don't believe everything that you think.
