Hmmm. On my server the post with the jpeg was deleted almost
immediately. Because of it's size, maybe?

Anyway, there is one of those, but it is on the other side. There are
two of these, presumably for the different settings on the charger?
Wondering why it would measure as a diode...
If it measures as a diode, then it is a diode. Are there two of them
connected to a center tapped secondary?

Are there other diodes, as well?

Yes, John, that is what they are connected to. And no other diodes, of any
kind. But the SCR bolts to the same heatsink, with the anode otherwise
unconnected. What have I got here?

Is it possible that they are dual diodes and the heat sink
rivet is the common cathode connection? I hate rivets as
electrical connections, but I have seen it done in low cost
consumer equipment. Common cathode pairs connected to the
phase control SCR (and over charge cut-off) this way would
make a working charger concept.
