was out in my car tonight and everything was going fine, was on my way home and the car started chuging like it was running out of petrol, then all the lights whent out inside and out side that car, just as i got home it cut out, as i whent outside ther was only one light on and it was very dim, when i go to start the car ther is nothing, the started dosent even click, but the alarm nd central locking still works, im thinking its the altinator but unsure, anyone had the same problem or simular, its a mrk3 fiesta, i know some of u are good with electrics on this forum so any help is great
