Checking the Diode should be a quick test with a VOM
(voltage ohm meter) at the car's J1772 socket with the car Off.
If you are not competent to do this test safely,
do not do it, and ask for help.
Measuring the resistance (ohms) from the Control Pilot to Ground:
1. Normal - around 800 ohms one way and megohms
with the measurement leads reversed.
2. Diode shorted - around 800 ohms both ways. Will only
charge with an EVSE that doesn't make the Diode check, like
the included Panasonic L1, or the AeroVironment L2.
3. Diode open - megohms both ways. Will not charge with
any EVSE.
