Hi, im new here and I really need some help. Tonight i got stranded and had to abandon my 200cui 66 mustang. While driving it died, I turned the key, and boom started right up, then I started driving again, and boom it dies again. I went to turn the key and nothing happened, i double checked the car was in nuetral (for the neutral safety switch) and it was. I then stopped the car and put in in park, just incase it didnt like neutral, and still nothing. It was at this point i realized...

1966 mustang electrical dead but battery is good
