Chapman has some sort of superiority complex. Sometimes a simple five word sentence would be clear but he likes to impress us with verbiage. I think he did too much programming when he was young. I certainly would visit a dealer and find out whats up. Its is unlikely to be your 12v. The car will run nicely on 11.5v but it does not have to once it goes to Ready and the inverter charge voltage takes the load.
