I'm having multiple charging errors since San Onofre went down - anyone else experience this for their Roadster. I'm having my electician check-out my 240V Home Charger > may need an added controller to prevent voltage fluctuations. My Tesla service advisor is warning about using the 240V cable and damaging it. Also will get a Roadster-J1772 adapter for charging at my work until this gets resolved. Any other thoughts would be appreciated.
