Yaesu CD-41 ESD Protection Mod

In this video, I discuss how the CD-41 charger can be fixed. I repaired the charger in the previous video but the design flaw is still present and needs to be addressed. I do this by cutting a trace, adding a series resistor along with a TVS diode. If you came here because your charger broke, check the write-up in the link section below. This might be easier for you than watching the video. Links: Repair video:    • Yaesu CD-41 Fast LiPo Charger Repair   Writeup: Available soon!
