Thank you very much I will check that out. Desoldering and resoldering relay will be no big deal but I have no clue how to restore a burnt pad. Any info on doing this ?
Once you remove the relay and clean the solder, you'll be able to see what the other side looks like. From what you've posted above I'm guessing that the pad in the picture is completely gone. If that's the case, perhaps running a thick copper wire from the other side, through the hole and soldering it to the trace and then to the relay pin will provide a reasonable repair. The key is to pick a wire that has the conductivity equal or greater to that of the trace.
Oh, and the wire on the other side where it connects to the trace will have to be insulated with some conformal coating to avoid any shorts when it gets in contact with the bottom of the relay.
