Im having my friend bring his sedan so I can swap the amp to see if that will help. Is it save to disconnect his L7 amp?
The fiber optic cable connection is part of the electrical plug with like 30 wires in it. The individual fiber cables can snap loose from the connector thus opening the MOST connection. Probably the easiest way to check is to look for a red light at one of the other MOST devices. MOST is a loop so every device in the loop passes the optical signal back out. If you pull a connector on say the AMP or MULF, or the CDC (assuming you have one) then you should see a light in one of the two fibers.
