Intellitec BD0 Relay
Now, if you follow the way Intellitec wants it wired, then the LED is "on" when the relay is closed and "off" when open. So if "off" then there should be no voltage on the system side of the relay... if there is voltage, the light will be "on" and I suspect a backfeed, wiring error, or something strange that Thor did. Follow their schematic.
