Easy Electrolytic Capacitor Replacement & Testing Methods

Electrolytic capacitor replacement (recapping) is one of the most common repairs on today's electronics. It's also among the easiest electronic repairs most DIY'ers will have no problem successfully taking on.
All you need is a soldering iron, a little soldering & desoldering skill and of course the correct value replacement capacitor/s.
Failed electrolytic caps are so common place, you can literally save hundreds of dollars in replacement electronic device costs, while keeping them out of the landfill &/or electronic recycling facility.
I'll show you how to visually spot a bad capacitor and in most cases, a visual inspection is all that's needed to identify a bad electrolytic cap. I'll also go over the values you need to know for your replacement caps, observing electrolytic capacitor polarity, and of course the actual capacitor removal and replacement process.
For those DIY'ers that have more testing equipment, I'll also show my simple capacitor testing methods when they show no visible sign's of damage. You don't need this stuff of course to replace a bad cap, it's just a little extra info for those that want to give it a go.
