I have attached to my Arduino a 2 Channel 12V Relay. Currently the red light on the Relay is working as my program switches LOW and HIGH every 5 seconds, so I know it's communicating. My 12VDC/AC power supply is plugged in the + is spliced in through the orange wire connected to the COM2. On the NO2 I have the +(pos) going to the pump. The -(neg) of the pump is connected to the power supplies -(neg). For some reason I get no response from the NO2 switching on or off. When the red light on the
