Since the DC-DC converter was blown and I didn't want to deal with it, I focussed on some other electrical problems I'd been having. Here's a look into the ashtray hole down onto the electrical contacts (just behind the black/blue and brown wires near the center of the picture).

I spent the evening debugging the small sparking issue I ran into yesterday. The behavior was interesting in that the keyswitch relay closed for about a second and then released. In the process, the DC-DC converter turned on (indicated by red LED) and then slowly decayed to the off state.

Apparently, I can purchase Lithium-Iron-Phosphate (LiFePo) packs from Electric Wheels in Salem, just an hour south of here for the whopping low price of $12,500 for a 100Ah/144V pack. Things might get really interesting with so many new electric vehicles coming out. I hope this will help with any emergency braking I might have to do.

Denial: "My new electric car is wonderful and it doesn't really rattle above 3500 RPM." and this could really screw up the electric motor bearings and the transmission. I'm an electrical guy, after all. Anger: "Why the hell does my car vibrate and rattle about 3500 RPM???!! It's not supposed to do that!
