I have a 12 volt circuit, switched by a relay. The (motor) load is 20 amps, when running, but I do not know what the start-up load is. I am going through relays faster than I can buy new ones. I have been told by some friends (who are NOT electronics professionals) that I need a diode to handle the spike in power, when the relay opens, and the magnetic field collapses.
Trouble is, I have no idea how to figure that out, as I am not an electronics savant. (I'm a painter, who likes to tinker...) Can anyone help me figure this out, so I can get the right diode?
I very much appreciate any constructive feedback.
