I'm using a JQC-3FF-S-Z relay that came in a kit with some soil moisture sensors and a submersible pump. I'm able to switch an LED on and off using the relay however when I connect the pump to the load side of the relay it begins switching on and off very quickly.
I thought at first the pump might have been drawing too much power so I isolated the pump using a separate power source and its still acting odd, im pretty stumped.
Has anyone encountered a problem like this? Is my relay defective?
