The charger works now!
I wanted to move the car, so I got in, powered up, pressed the throttle and it dropped out. Repeat, same thing...
Aha! The master contactor isn't closing! The master precharge relay was closing, but it was trying to pass big voltages across a 200 R resistor inside the pack. No go.
Why was the master contactor not closing? The precharge delay timer I bought off Alibaba stopped working. Good thing I put it up the front so I can access it. Since nothing capacitive is being powered from the battery at this stage (A/C compressor will be a while off) I just omitted the precharge delay and turned both on at the same time. And it charges, drives, and works as it should!
