Are these normal electro-mecanical relays? Are the contacts isolated from the coil and cape?
There are also toggle relays, which require a positive coil voltage to set and a negative coil voltage to reset. You are NOT using one of these? To test the coil side. The cape drives the coil and you can normally hear the contacts switch when the coil is energized or denergized. The posts before where trying to test the contact circuit. Without the relay, does the battery light the lamp/LED? Without the relay coil energized, does the battery light the lamp/LED through the relay COM (common) and NC? With the relay coil energized by the cape, does the battery light the lamp/LED through the relay COM and NO?
