Ford focus mk3 2012 absolutely dead dead
Hi, after a short 20 minute drive I tried to turn the engine on (a bit quickly) and it caused everything to completely die. There was a warning light and ping for a few seconds the second time i tried but then everything died. A few times after that i had some weak LEDs around the radio display blink and any time after that there is zero response, not even able to lock it or put hazards on.
Is this a blown battery or a blown mega fuse or potentially both? Ive replaced the other fuses alongside the mega fuse (different available delivery) to no avail so far.
Ive had current issues for a few years with drops and surges in power to all systems (headlights, interior lights, display, fans/AC) so I assumed once it went it was a cracked, now blown, fuse. Im going to replace it today but does anyone have any suggestions for what else it could be?
