  • 1999 S250 ox66 voltage drop

    Installed new batteries and cleaned the cable terminals. Went for a test drive and started out at 12.4 volts and after about 30 minutes the voltage indicator on my speed gauge would drop, by the time I got back to the dock it was reading 11.2 volts.
    Any ideas......I am thinking maybe the rectifier/regulator or the stator but don't know how to check if either is not working.
    Would appreciate any help !!!!!
    Thanks

    i checked my output by running on hose, unhooked batt and used a voltmeter on pos and neg coming from motor.
    try unhooking EVERYthing else from boat except motor and see if the voltage still drops
