    battery problem , plz help .

    hi everyone

    today i installed a new battery in my sky .

    after i installed the battery the sky was starting like it should , BUT i noticed that every time that i start my ski the gauge screen would display low voltege warning in the dash .

    after two hours of riding i tried to start my ski but it wouldnt start at all , then i took my ski to put it on its trailer , and then i i hooked up my laptop to my ski ( i have motec ecu ) to see if there's a fualt codes but there wernt any codes , then i saw the battery voltege it was 10.4 !!! the battery was 13.6 when i got it .

    what could be the problem ? stator assy ? or elictric fire ?

    Not sure if it was that way when you purchased it (it sure seems that there was an initial problem under load) but I'm concerned that the battery, despite being new, is now sadly toast....

    When the ski was running what was the voltage at the battery? Battery is in need of a charge now. probably wont be able to get it back. Take it back to wherever you got it should still be under a warranty of some sort.
    Put the new one in and check the voltage at across the batter with it running> Should be 13.5 or therabouts.

    i pulled the data out of my motec to see the battery voltage , if im cruising at 5400 rpm the voltage is 11.1 BUT when i hit full throttle the voltage drops to 10.8 and if the ski is on idel the voltage is 11.4

    i attached two pics of my data log

    your conversion is wrong bro, if its 266 kpa you remove 100 so the number you need to convert will bee 166 kpa that would be 24 psi .
