What was found
THE PILOT REPORTED A LOSS OF VOLTAGE INDICATION ON THE MFD WITH ALL OTHER SYSTEMS OPERATING NORMALLY. THROUGH TROUBLESHOOTING IT WAS DISCOVER THAT WIRE #ANEN983-22 WAS CHAFFED THROUGH THE INSULATION (THE AREA IN QUESTION IS LOCATED ABOVE THE CO-PILOTS KICK PANEL AND BEHIND THE RIGHT HAND INSTRUMENT PANEL). THE AIRCRAFT RECENTLY HAD THE X-M WEATHER KIT OPTION INSTALLED. IT APPEARS THAT WHEN THE KIT IS INSTALLED IT IS POSSIBLE FOR THE WIRE HARNESS TO BE MOVED TO THE POINT WHERE IT CAN CHAFFE ON THE X-M AFT MOUNTING BRACKET. SINCE THIS IS DIFFICULT TO SEE ANTI-CHAFFE MATERIAL SHOULD BE INSTALLED ON THE AFT BRACKET TO ELIMINATE THE POSSIBILITY OF THIS CONDITION.
