    Diagnostic 9 low volts

    Became another statistic of car vs bike.(Not the FZ)
    4 months later back to trying to get this FZ sorted.
    Display reading just over 5volts.when in diagnostic mode 9
    Battery charged and tested, Kill switch continuity fine.
    First time this has occurred and previous issues aside, finally got it tick over issue free.
    The only electrical components not tested are the wiring loom and the ECU
    Any suggestions please.

    Re: Diagnostic 9 low volts

    While reading the voltage on the display did you also measure the battery voltage with a multimeter?

    Re: Diagnostic 9 low volts

    To test the battery it should be fully charged and then load tested. Don't jump start the bike from a car if the car engine is running or you may damage or destroy the regulator rectifier assembly. What are your charging voltages?
    If you can't fix it by hitting it with a hammer, it's electrical!

    +100^^^.

    Yank the battery, charge it and load test it- Basic's first..


    *Just curious, how did you "test" it?

    Re: Diagnostic 9 low volts

    Thanks for the replies. As the basics have been covered it's components that effect the return path to give this 5.3v on display.
    Although the bike won't tick over due to loss of cylinders, cranking is not an issue or loss of ignition to any cylinders. So protection mode but no fault codes.?
    Working my way through the manual, is the diagnostics in the ABS applicable here.

    Did you LOAD TEST the battery since last posting??

    I take it, NOT answering, you didn't load test it, (especially when checking voltage thru the dash and NOT at the battery itself.)

    And how did you test it before?

    Sounds like it may be a fuel issue,

    If the bike sat for a while a rodent may have nested and gnawed through something.

    I'd like to confirm the battery is good before jumping about. Seems we may not know...

    That, or he did get it load tested, found it to be bad, replaced it and disappeared..


    Lastly, if someone can clarify:

    Quote "return path to give this 5.3v on display. Although the bike won't tick over due to loss of cylinders, cranking is not an issue or loss of ignition to any cylinders" End quote..

    Is the engine spinning over normally, just not firing off?

    I agree there seems to have been a problem in articulating what the issue was. At first I thought there was a problem with source voltage. Now I believe the op is saying there is another problem. The motor turns over okay and there is spark but it does not fire.
    Now I'm thinking a fuel problem possibly related to electrical in relation to the ECU or wiring. Talking about fuel. What condition is the fuel?

    Re: Diagnostic 9 low volts

    If there is a fuel problem, confirm there is 12vdc nom. at the fuel pump and fuel injectors supply. This voltage comes from the same fuse through a relay in the starting circuit-cut off relay assembly. If the bike starter turns over the engine but you have no injector or fuel pump, check for a blown fuse and then insure you have voltage from the starting circuit-cut off relay assembly. The wire color code from that assembly is red with a blue tracer. Another simple confirmation would be hearing the fuel pump prime sound when the key is turned to the on position.
    Do you hear the fuel pump prime?
