Am I right in thinking that if the car won't start with the battery charging, it's not the battery thats the problem? (Battery did seem a bit dead according to the charger)
I’d say no. Battery may not have enough charge to start the car. May be the battery has died. Does it sound weak when you turn the key? Like it’s struggling?
Not sure - if battery is completely FUBAR it might not deliver enough current to the starter motor even if it's on charge? Can you hear the solenoid click when you turn the key?
