13BRV3 -> sonic charge balance cable connections? (5/3/2007 12:15:55 AM)

Greetings,
I have a Sonic Charge charger, and several 3s balance cables that I just received from A123. I also have several 3 cell A123 packs ready for final assembly and testing. The problem is that I don't know how the how the Sonic Charge balance cable wires are supposed to be connected.
There are two wires on the balance cable, one white, and the other orange. One of these will go at the junction of the 1st and 2nd battery (3.3 V above pack ground), and the other will go between battery 2 and 3 (6.6 V above pack ground). The question is which one goes in which location?
I noticed that the 2s cable only has an orange wire, where the 3s cable has an orange and a white. Logic would suggest that the orange will go at the 3.3V level, and the white will be at 6.6V. Unfortunately, logic isn't always logical, so I'll try to hold off on testing this theory until I get an informed answer [:)]
I emailed A123 yesterday, but got home today, and found no reply yet, so if anyone can tell me where the wires go, you will become my favorite person for at least an hour [:)]
Thanks,
Rusty
