I finally got the led to go on by connecting from blue/white wire, through led wires, back through the other blue/white wire, in series. This didn't turn on the led before but now it does; however now the warning light doesn't work! This would be okay with me, BUT might be upsetting the balance.

Better would be to have both lights go on, in parallel, in case the led fails, but the led doesn't go on that way.

Update: I drove the car around my 2.7 mile loop, the alternator was charging and all appeared to be well. However, the led was harder to see than the battery light, so I've reconnected the battery light back to the way that it was.
