You could try connecting the electrical ground (first make sure you have one - test with a meter from the hotel on an outlet to screw on an electrical box) to the power supply ground screw.

When a call comes in from the channel bank, does the light flash at 60 ipm? With dial tone on the line and the phone off hook, short the A/A1 leads. Does the lamp light? If it does, try removing the short; the lamp should go on hold.

It does sound like your interruptor is not working. You'll have to check the prints. Bridge 10VAC to the interruptor motor and see if it starts.

That's all I got now...
