I've replaced my corner lenses tons of times, I never bother turning off the battery in my car, who cares. However the other day my dumbass was pulling out my alternator to repair it and forgot to turn off the battery and my socket wrench touches the + and then the ground and I blew a big ass 60 amp fuse. No damaged done except a big blown fuse which I replaced. But I guess that is a good reminder to me.

Also that Hazard fuse will have reset your ECU and all that good stuff. Because I know to reset the ECU you pull the hazard fuse, so I assume blowing it would do the same thing. Turn your car on and drive until it is warmed up. Then turn off the car and pull that fuse again for like 10 seconds. Then plug it back in and run the car for like 10 minutes. That way your car will re-learn its fuel maps and your car should run a bit better.
