Checking a fuse
Is it possible to check if a fuse is working using a multimeter?
Our iBoost has stopped working and there is a fuse where it's plugged into the mains. It's a 13A fuse and I don't have a spare to hand – wanted to see if it's the fuse or if the iBoost itself has died.

If your multimeter has a resistance range, then remove the fuse and check for continuity. If the reading is showing open circuit, then obviously the fuse has blown.
Another simple way is to fit the fuse to a different item of equipment, lamp, hairdryer or similar, and check that it works. Obviously, don't fit a lower rated fuse to equipment with a higher operating rating.
