Insight pack internal connections

Wanted to do some charger/discharger test on a pack that was pretty bad, so I took off the covers, and made this chart, which should be a nice road map for any battery explorers.
Adding the jumper across where the big fuse and switch was located as shown here removes any protection from shocks or short circuits, so proceed only if you know what you are doing. May be better to use a DC rated fuse in the jumper to maintain short circuit protection.
