Hi there I brought a new battery today for my car, I put it in didn't start then put a booster pack and it started when I did that the day was warm not cold. Now it's 7 in the evening really cold frost on the car and the car don't start with the booster and other good battery.

Is any one having this trouble like me?

Could it be that the alternator or the starter motor is faulty, when I do press the start button it makes a knocking nosie and it was trying to start you could hear a whining nosie too?

I think it's the starter motor

Can you guys help me please it's doing my nut in now lol.

Cheers ash
