I have the datasheet for a relay I'm using, and I know what the polarity is.
However, what if the datasheet was not available, I can find out which contacts are supposed to by powered from a supply just by the resistance. But how would be able to find out which way current is supposed to go?
Here is the relay I'm referring to: http://www.futurlec.com/Relays/HFD31-12.shtml
