The low voltage part goes from the controller panel to the transformer.
The high voltage part goes from the transformer to the magnetron going through a bigass capacitor.
The capacitor has a ground connection to the base of the microwave machine through a diode that can only be tested while connected, and this is the tricky part where you can put your entire body to 24000v in 1 second.
Also the magnetron has BeO2 which is toxic.
