Hey, Kilmer my 2007 Dodge Charger randomly turned off in the middle of the freeway about few months ago. It was terrifying I could’ve crashed and died but I pulled over on the side safely by just using my brakes and steering wheel. I tried putting water in the radiator and charging the battery but never turned back on, so my buddy had to hook it to his truck to get it to my house. Recently my buddy who is an ex mechanic took a look and he said that he’s for sure is the alternator because the battery works we took it to a store to charge it but the car still doesn’t turn on. I mean it cranks weird like A scratchy noise. He also said that the fuel pump is good and all my injectors are new. My radio turns on and light as well. All I know is that the alternator helps charge the battery while is on. So this is my question? Is it the Alternator?
