Been giving it my all in the rain.
Charged the Leaf battery until the charger cut off at 13.01v. Hooked booster cables to it and while the ICE was running, the Leaf Battery showed 14.26v. Cleared the codes several times, but always came back. I even cleared the codes and hooked the charger to it before starting and always the same result. Tries to communicate and then disconnects. The same inside when starting. It starts out with no warning lights in the dash, but as the car goes through its checks, the car with a mark through it reappears, indicating the high voltage error. I have reached out to a YouTuber who had a bad resistor and asked if he saw range in the car when he had the problem, but I don't think so because he indicated you could check it another way by removing the high voltage connecter from the battery and insert the probes into the battery and if you start the car, you should see 400v for a second or two on the meter. Sounds like a crazy plan, but that is what he said was another check without taking the battery apart. He had none. So, if he showed no voltage at the battery, it seems like the car GOM wouldn't be able to read the pack. Of course, I know nothing about this and why I am on here.
