Well, I attempted power up this morning. Nothing blew up which is good but I got a communication problem and couldn't pull firmware info from the inverter. I have BMS info coming to the controller though so it's not a CAN1 problem. I started digging around wiring and found a broken wire for 'CAN2 Low' at the controller connector. Hopefully that's the problem and I didn't just break it while checking. However - I can't get the bad terminal out of the main connector easy. Last time I tried to hack job it I broke the housing. No choice but to order the overpriced terminal extractor tool, so it'll be a few before I can fix it and try again. DigiKey has it in stock but I have to go to Oregon for work this coming week so realistically it'll be next weekend to fix the broken lead.

Meanwhile I should be able to test out charging, and there's lots of other things I can do of course. Will probably work on getting the brakes filled and bled.
