Narrative:
[I had a] mechanical malfunction of the [landing] gear caused by a wire being shorted after an avionics upgrade to a new garmin G500 multifunction display with synthetic vision - a short between the gear indication lights and gear activator switch. Right main gear did not lock but showed a green light. Right main collapsed after landing which tripped fuse on landing control. Pump failed before it had sufficient pressure to lock landing gear completely. The left main and the nose gear did lock but the right main did not lock into place.
