I've replaced most of the easily blown fuses in my car (accessories, etc.) with PTCs. Now I joke that turning the car off and then on again fixes the problem. However, I wouldn't do that with a vital system (starter motor, etc.) because a blown fuse generally informs you of a deeper problem, rather than being the problem itself. http://en.wikipedia.org/wiki/Resettable_fuse http://en.wikipedia.org/wiki/Resettable_fuse They make these in automotive format, or you can go to Digikey, get a PTC of the current you like, and solder it onto a blown fuse. PTCs have the advantage of being straight replacement, and if you want, you can add a Hall sensor to see if current is flowing without creating paths to ground or other problems. Anyone knows how to add this answer to Woz's thread? The "awesome power of social networks" isn't that awesome, since I can't answer on the thread linked...
