You may not have one! Do your interior lights, the water pump and the furnace work? Those things are all on 12V and would be "enabled" by the Master Switch when it was flipped to the position that disables the lift motor. Conversely, if the lift motor is enabled, those things would be disabled by the Master Switch.
So, if everything works at the same time, you don't have the Master Switch.
