What should my battery voltage be on a 951Di 3D? Its currently 12.1v when motor is not running, 12.3 at idle and goes to 12.9 when I run the motor and rev it up. I am having fuel pressure issues with a new pump and wonder if it could be the battery.
Your battery voltages are just a little low but not low enough to cause the problems you hare having. Below 10 to 10.5 volts would be a problem. Generally if the ski will start your battery is O.K.
