Hi everyone,
I have a ground switching circuit that I needed to change to a positive (for fans). So I went with a relay to convert the negative output to a positive output.
So I wired in the relay and its working. BUT I noticed that on Terminal 85 which is my negative trigger coming from the the controller relay, that it shows 12volts all the time until the negative trigger is activated. So my relay is feeding power back to the controller.
The relay has 12v coming into it via 30 and 86, now is it also normal for that 12v to travel out of pin 85? I know once the controller relay give it a negative trigger, power exits out of pin 87, but I don't know if its suppose to show power exiting 85 all the time.
