The 322-8BH10 has diagnostic capability to detect a broken wire connection to the relay. It does this by applying a small pulsed current of less than 1ma to the circuit when it is in the off state. This is why your LED is on dimly and why you see a voltage when the output is off. You must have a minimum load on each output of 5ma. A 1/4W 4.7K ohmresistor acorss your relay/LED indicator should solve your problem.
