DIY Guide to Constructing a Capacitor Discharge Tool for Unknown Device type
Duration: 45 minutes
Steps: 6 Steps
Capacitors are those nifty little electronic components that you’ll find in nearly every gadget with a circuit board. Just a heads up: larger capacitors can pack a punch and store enough charge to give you a jolt, so it’s super important to discharge them safely. In this guide, we’ll walk you through crafting a simple resistor-based capacitor discharge tool. Let’s get started!
Step 1
– Ready to whip up your very own capacitor discharge tool? Awesome! First things first, let’s round up all the materials you’ll need for this little adventure.
Step 2
For a rock-solid solder connection, make sure to strip at least .25″ of insulation from the wire. You’ve got this!
– Kick things off by peeling back one end of each wire length. Let’s get to work!
Step 3
– Now, let’s give those leads a little haircut! Trim them down to match the length of the insulation you stripped off in the last step. You’re doing great!
Step 4
Make sure there’s plenty of solder flowing through that wire to form a solid connection between the two parts. You’re aiming for a bond that lasts!
We’ve got a sturdy wire on our hands, so we decided to pop the resistor lead right down the middle of the wire’s conductor. Then, we twisted that wire around it as snugly as we could. Just like a cozy hug for your electronics!
– Twist the stripped end of the wire together with the lead coming from the resistor – it’s like they’re shaking hands!
– Now, let’s make it official: solder that wire to the resistor and seal the deal!
Step 5
– Slide a piece of shrink tubing up the wire, ensuring it completely hugs the solder joint and any exposed wire like a cozy blanket.
– Grab your heat gun or lighter and gently shrink the tubing over the joint, making sure it’s snugly covering all the exposed wire for a neat finish.

Step 6
For those tricky small points, try giving the exposed wire ends a little snip to form a pointy shape and solder them down to keep that shape intact. If you’re feeling fancy, you can also solder the probes from your multimeter to the wires for a snazzy, precise discharge tool.
When dealing with big electrolytic capacitors in power supplies, electric motor start circuits, and those flashy camera units, consider soldering one end to a hefty alligator clip and the other to a well-insulated screwdriver. Safety first, but a little creativity never hurt!
– Now, let’s go ahead and repeat that process on the other side of the resistor. You’re doing great!
– To finish up your discharge tool, simply strip the ends of the wires. You’ve got this!
