    Your latch looks secured and on properly, I wonder if it’s the big plug that you removed from the inverter that isn’t plugged in properly for the engine to run. I think your 12v battery seems to be fine because it turns on and the lights doesn’t look dim. I’d recheck the orange wire side to see if things aren’t plugged in properly or the engine side where the connectors aren’t plugged in.

    Yeah, I've already unplugged the battery and removed the safety pin. Will wait for the capacitors to drain (they probably have already) bust out the screenshots of the manual and check the inverter. That dr. prius app shows that the hybrid batters are good, which is great. Thanks for the callout!

    If that does not work disconnect the high voltage at the compressor, inspect and try with it off after a 10 second 12v disconnect. The 12v cycling can be done at the fuse box by unplugging the white cable on top. Realize a Ready usually takes a couple of attempts after cycling 12v as the networks establish.

    This video at 28:50 shows the inverter cable installation and the cover interlock connector.

    Good tips. Thanks.

    EDIT: Ok. I never knew about this high voltage clip. Wow. Learn something new every day! Thanks again for the tip.
