Tried out the relay function on my Global link 520. It was working good, I could hear the click and could measure the circuit open and closed as expected.
Then it seems it is not working any more, I try to open and close it using the VRM app, with blue tooth connection but there is no difference, no click and relay is open all the time. I read in another thread that the relay is rated for 3A. What happens if you exceed that? Is there any internal fuse or is it permanently broken?
