September flew by in a blur of laziness and lack of motivation, I guess.

Hurdle du jour: I went to the junkyard and got enough battery cables/clamps to make a securely connected 48v pack (instead of a tangle of jumper cables like last time), which we strung together this evening from a combination of boat batteries and old starting batteries.

We hooked up my eBay Curtis golf cart controller. There was a big spark making one of the connections, which we weren't expecting. And then! We couldn't make it work.

So we quit this evening not knowing if it's the controller or the pot that's not working, or if we somehow fried the controller. I believe controllers "charge" before they go into action, so that may be the source of the spark.

I've got a question out on the Citi/Comuta Car list, since they often upgrade to controllers from their contactor setup.
