Introduction: Replaceing a Soldered in Fuse.
Some times replacing a blown fuse isn't as simple as it should be.
Step 1: Why Do They Solder a Fuse Streight to the Board?
I started using a 3D printer and managed to ruin two power supplies. The first one blew a component so I bought a larger one to address the power draw and it was working fine until I goofed and pluged it in a little to fast and blew the fuse (no on/off switch which was addressed later). The fuse in the power supply (like the first one) was soldered in and to replace it I would have to remove the board. Some of the components on the board were fastened to the case and I didn't want to mess with that. Expecting I may blow another fuse down the line I decided to put in a replaceable fuse.
Step 2: Check You Options
There were a couple of options for this, one was an external fuse holder that I would have to drill a hole in the case for but I didn't like that idea. I found a fuse holder that fit the fuse in the supply. Because this was the same size holder it just clipped on the fuse upside down.
Step 3: KISS
There was plenty of space to put a standard 1/4" fuse holder on the board so I opted for that.
Step 4: KISS Again
I could have used quick connects for the wiring, but chose to solder instead. A little heat shrink to make it tidy and done.
Step 5: Easy Is Some Times Best
Not wanting to drill into the board I opted for gluing the 1/4" holder. RTV Silicone work great.
Step 6: Almost Done
After the silicone had time to set all that was left was to connect the small fuse holder to the fuse.
Step 7: Happy Ending
All that was left was to wire and test. Green light is good!
