    2008 SHO 1800 FX - Not charging battery

    Hi all,

    FX SHO Started with a good battery, dash started beeping at me, Voltage display showing 11.9v while running, by the time i got back to shore it was showing 11.7v, no codes were being thrown up other than 01.

    I have been told that best place to start would be the earth block, i have limited space to work so before i start pulling bits off my engine can someone please explain to me where this earth block is please? im pretty sure its the regulator/rectifier but might as well check the block, do i have to pull anything else off the engine to gain access to it?

    Thanks in advance.

    Battery is deeply discharged at anything close to or below 12.0 volts. Battery should be recharged using a good charger with smart ‘float voltage’ control.

    Then restart engine and check battery charging voltage, using a multi-meter on the battery posts. If engine is running and battery voltage is not well above 13.0 volts then the charging system is not working properly.

    A traditional old-school lead-acid battery will have a fully charged resting voltage around 12.5 volts. A modern AGM battery when fully charged will rest* at around 12.8 volts.

    * For battery charge measuring purposes, resting voltage occurs when the battery has been left sitting (no charger connected) for at least 24 hours.

    Worst case scenario bolts could have snapped on starter ring destroying the charging system ( yes I’ve had it happen )
    If it’s the earth block
    That’s located on the back of the motor right hand side
    You can get to it without pulling everything off
    It get corrosion build up
    But I think rest of power systems would be playing up as well

    Member recently had some earth block issues... I have same year ski and have had battery wire issues too....

    they are sensitive to high impedance issues the stator can be tested get the service manual or book it into dealer.... ££££
