I'm totally useless in electronics and electrical matters, so I need your help to solve this matter.
Purchased two different wireless 433 mhz relays; one to act as an ON/OFF system and the other that has a programmable timer so I can activate a 12 V water pump either by starting and stopping as I wish and the other to last me 4 minutes and then stop. The pump and both relays are all powered by a single 12V battery. Problem I find is that even though one relay works like a charm, the moment I connect the other, and before I activate anything, the pump starts running without stop, till I remove the ground of one of the relays.
Searching in the web I came to this forum and saw something similar in one of the topics I can't find now, and just wanted to "use" one of the forum members drawings to show a fairly similar situation and ask for permission to use and modify his dwg. to suit my situation; the thing is I can't find it now, but hope he/she doesn't mind me using it.... Thanks anyway.
Best regards from Spain to all and hope you are all doing well in this actual pandemic : (
Let's see if someone can help me out.
