because im an idiot. Fuse before or after reconnecting battery.

Does it matter if your fuse is in and then you reconnect the negative.

Or should you have the fuse out and then reconnect the negative and then put the fuse back in.

Im not sure if it matters but i like to ask silly questions and see just in case.

Have the fuse in before you reconnect the battery.

If you're talking about the inline fuse, it doesn't matter.

If you have it in, the wire is protected by the fuse. Worst case scenario it'll blow, protecting the wire.

If you don't have it in, the wire's protected since there's no continuity. Once it's put it in the above applies.

Really this applies to any fuse that breaks up a circuit. Fuses work by severing a circuit to protect elements down the line. No fuse, or a blown fuse, and you don't have a complete circuit.
