Hi! I can’t get my MK188 to work, when the relay activates, it give the pump 1 sec of power and same time it “clicks” and then turn off. I’m trying to use it with a water pump, and that has a max of power of 12V 11A. It says that 16A is max so it should be enough?
The relay works with no load but as soon as I connect the black minus cable thru the relay it “dies” when the relay activates.
I have a short clip of the event if that helps, here you can here the click sound in the begining, on my onedrive:
Edit: You can notice that the powersupply (that is an psu from a computer) turns off just when the relay switches, like it’s a short cut? But I have mesaure with multimeter and under no load I get 12v thru the relay. I have tried to power the pump with just the PSU directly and that works.
