    Tesla swapped out my charging cable as it was only charging the car to 60% I plugged in the new one today and the rate oif Charge seems extremely low.
    Any ideas

    Then I would give Tesla a call and ask. They should have some way to pull the logs.

    By "charging cable" I would assume you mean a UMC.
    Assuming 50A outlet, it sounds like the 14-50 adapter at the end of the cable has the wrong resistor in it.
    16A is what you'd get with a 5-20 adapter. You didn't make an adapter and plug a 5-20 into a 14-50 outlet did you?
    If wall connector, check dip switches.

    I would find another 14-50 outlet and see what it gives you. I was under the impression that the car has a way of testing the current load and will back off the power if it feels the circuit is over loaded. So it could be that logic in the car or the circuit.

    Interesting. 16A is what I am getting on a Model S with a messed up charge port (lock pin won't latch). I assumed that it was some sort of default current, even when there is a problem.

    Are you in the US? And where are you seeing this charging rate, at home or at a business?
