    Low voltage warning.

    Ok i will try to make a long story short guys. On water this morning take off all good,start to trim up and get low voltage warning get to spot and check smart craft. Volts are good and alternator is working great. Happens periodically through out the day still everything else is fine.
    This is where it gets interesting,on the way back to ramp its kinda windy and choppy go to cut across boat wake and hit it pretty good. Its like the motor just shut off and came right back on in a second, was freakin out back to ramp but it ran fine and rpms were good. Sounded great and idled fine. Checked all connections and they were good. 0421xdc simonized 250 xs.Any ideas fellas?Think i will just take it in.

    Re: Low voltage warning. (easymunz)

    Good starting point:

    LOAD TEST BATTERY.

    Verify battery capacity and type against the following list:

    Confirm battery terminal connections are CLEAN, ENGINE CABLE INSTALLED FIRST, remaining lugs "Largest to Smallest". Connection should be finished off with a Stainless Locknut (do NOT use Wing-nuts).

    Verify connections of battery cables at the ENGINE end of the cables are clean and tight.
