2004 Kia Optima 4 cyl Front Wheel Drive Automatic 106000 miles
This fuse blows intermettenly so I have not been able to drive the car for 7 weeks. Several mechanics have given up as they cannot reproduce the conditions to make it blows. There does not seem to be a pattern I can detect yet.
A wire comes off the alternator plug, through the 15 amp fuse, on to the computer. When it blows, it shuts down spark and fuel. It all started with a blown computer. I replaced it and it started right up but then started popping fuse as soon as you put them in, the 15 amp ecu fuse. I found a burnt wire leading to the fuse under the relay box on the fender, repaired it, everything seemed fine. Then the intermetten fuse blowing just when you don't want to be stranded. I can let it sit in my driveway and the fuse does not blow.
Could it actually be something as simple as the alternator going bad?
