I had reached a dead end and I wanted a "known good" charger to compare readings against. I ordered another charger from eBay. It was advertised as "Works great!"

It did not work. I took it apart and it was in worse shape than my charger. Either battery electrolyte or water had gotten in to the charger and eaten the PCB traces and several components. It looked like some sort of insect infestation had occurred as well. Amazingly, I managed to repair it and get it working! I had to use a few components I had in my shop, but it works! Knowing the repair work that needed to be done, I would not feel comfortable selling either one. But I guess I have two working chargers.

Note

Even with the left side USM1 diode internally shorted, the charger still worked charged my battery twice.

Both broken chargers
