Bad luck
Tonight I took the Mustang for a little drive and for the first time ever, it died on me just as the light went green and I wanted to accelerate... It would crank but not fire so I had no choice but to push it to the side. Thankfully a friendly motorcyclist helped me out. After waiting for road side assistance for about 4 hours (it was a hot day and they were really busy) they showed up. I told the guy I thought it was the ignition and his first guess was a blown fuse. So we looked (I never looked at my fuse box before) and what do you know? A fuse had blown! So he thought he'd quickly replace it but that didn't happen, well, the fixing did but not quick ;-) He had to manufacture a fuse because he had none that fitted which resulted in the construction below.
The fuse that was in was 30A I believe... That's a LOT!
It was late and I left the car in my garage. More later...
At home I looked up the fuse box. Apparently it only needs a 14A fuse which I had to order...
Meanwhile I was wondering what was causing the short. Although I was able to drive home, soon every fuse I put in blew as soon as I turned the key to the ON position, not even starting. After playing the elimination game the culprit appeared to be the ignition coil. It was also double wired which was odd.
So I spent a couple of nights studying the electrical diagrams of my car and figured out the correct way of wiring the coil.
I also ordered a new coil and wired it according to specs. Haven't had a problem since :-)
