yes you did say that.....it could be a bad low voltage sensor i have nerver seen one go bad as theres no much to it but i imagine they can go bad......if it were mine i,d start there......open up the charger and clean the spade terminals maybe they arn,t making a good connection......i,m trying to imagine what all is in there since its been a while since i opened one.....................i have a few books here i,m gonna look to see if they show the charger innards it one of them.....you said the charger did work before? ...............................................
