Could this be a problem?

I was adding the headlight relay mod for all 4 headlights at once, and had hooked up my ground wire to a nearby chassis bolt. While running it back towards the battery, the wire slipped, and made contact with the power terminal at the fuse-box!

A little spark show later, everything seems to be fine, though I couldn't get the courtesy lights to come on...
So, I pull fuses, and get out the multi-meter, and before I get too far, they magically go back to working!

My concern is that with the C5's notoriety for electrical problems, do I need to worry?
