Sounds like it could be due to a stuck relay or an emergency bus switch being activated. According the Lear 31 wiring manual, these three items could be tied together on an emergency bus, but it is dependent on how the aircraft is wired. The Lear 31 wiring manual refers to the custom avionics wiring diagrams. I would recommend you look into these drawings to find out exactly how this particular aircraft is configured.
