The batteries were discharging over the winter and didn't seem to keep the charge I was giving them. So I figured the batteries where damaged and bought new ones. While I was connecting the wires from the charger to the new batteries I saw a spark, which surprised me. I checked to see that everything was being connected correctly, and it was. So I used my multi-meter between the battery terminal and the charger lead and found 4.26 Volts was going thru the charger.

Hi Steve, I must have missed the history of the issue but I like to hear it again if you don't mind. "Completely discharged battery" failure mode has hit me several times and I have become sensitive to the issue. First episode was my wifes bran new Dodge Avenger ending up with a completely dead battery in the garage. After determining the dome light stayed on if the door was not completely closed. I chaged the battery and figured we will just be careful and close the door properly from now on. A year later another battery dead as doornails due to same root cause. My Jeep Cherokee ended up with a completely dead battery at the workplace parking lot. I went to my boat hoping to have a nice day of sailing and found the battery completely dead. After I wised up about this issue, determination of the exact root cause, and taking effective corrective action became important for me. After that long story, let me ask my question : What testing did you do to make the statement "The battery charger's blocking diodes appear to have failed"? Replacing what "appears to have failed" does eventually work but not usually the most cost effective way to correct the problem. Just trying to help.
