First, let me say that the battery was put on charge friday, not tested until monday, second, my fluke meter was taped to the back of the mast in plain view from the seat, not puttiong anybody in danger, third, I put the battery on charge for 45 minutes to establish a base line for the failure, ie it changed the timing of the failure by increasing only the state of charge. Thanks again for your input, bottom line... bad battery, I'm a mechanic not an operator, so i'm familiar with charging abuse, this is an old truck with an old battery, and today a tight pocketed customer.
