I was having issues with me EVSE charging my volt so while troubleshooting I applied 12v to the relay with it still attached to the openevse board when I heard a pop and smelled the familiar smell of burnt electreonics. I removed the board and found what looks like I blew the q3 relay transistor. I would like to just replace this component. My question is what is the part number for this? It has K1p B2 printed on it but when I search that part number I cant find anything. Can anyone help?
