Testing the electronic expansion valve coil of the Daikin Ecoswing R32 Smart inverter air conditioner. I POWERED IT WITH 12VDC, WITH THE POSITIVE IN THE GRAY AND THE NEGATIVE FOR EACH WIRE, ORANGE, RED, YELLOW AND BLACK. IT PRESENTED A CURRENT OF 240mA, but as the yellow one is short-circuited, it did not present any current. I tested it using an adjustable source from 0 to 30V with short-circuit protection.
