Well, the charger + battery in parallel (+ to +, - to -) would be 12v with chargers amps + the battery's amps. With the charger + battery in series (charger + to starter, charger - to bat +, bat - to engine ground) would be 24 v + amps. The point in putting the charger on in parallel would be to see if it starts with the chargers amps, which would prove the battery doesnt have enough amps. A battery can have 12v with a fault and not have enough amps to start.

thats why i was saying to use the jumpers. so anyway i was forget full bat 12v with chargers 12v still equals 12v its just the amps that are doubled right? then if NOT SAYING TO DO but if bat + to chargers - = battery volts + charger volts?
