What Tesla says to do
Electrical safety. Tesla ties this light to the power supply, earthing or an electrical fault, or its own steps use the circuit breaker, fuse box, RCD or isolator. The steps here are only Tesla’s own, as its page states them; semiatic gives no electrical instructions of its own.
- Tesla says: turn the circuit breaker off, wait 5 seconds, and turn it back on.
- Tesla says: if the solid red light remains, note the part number and serial number, then contact Tesla Energy.
Connector: these lights are from Tesla’s manual for the J1772 (Type 1) version. What that connector’s label means is on its own page.
