ON THE DATE INDICATED, WHILE THE MOTORHOME WAS PLUGGED INTO 115V 30 AMP A/C POWER, WITH ONE ROOF AIR CONDITIONER OPERATING, AN ELECTRICAL FIRE OCCURRED IN THE JUNCTION BOX. THE FIRE, APPARENTLY CAUSED BY A SHORT CIRCUIT, CONSUMED A CONSIDERABLE AMOUNT OF WIRING INSULATION. FORTUNATELY, THE FIRE DID NOT SPREAD TO OTHER MATERIAL. DAMAGE REQUIRED REPLACEMENT OF THE POWERTEK BREAKER BOX AND REPAIR OF THE WIRING. THIS WAS THE SECOND TIME THAT THIS HAD OCCURRED IN THIS MOTORHOME. A VERY SIMILAR ELECTRICAL SHORT AND FIRE OCCURRED IN JULY 2000. DAMAGE WAS NOT AS EXTENSIVE AND ONLY THE WIRING NEEDED TO BE REPAIRED. THESE INCIDENTS ARE BEING REPORTED TO NHTSA AS A SAFETY HAZARD. OTHER OWNERS OF THE DISCOVERY MOTORHOME HAVE REPORTED SIMILAR INCIDENTS. FLEETWOOD HAS REFUSED TO PROVIDE ME WITH ANY FINANCIAL ASSISTANCE TO CORRECT THE DAMAGE RESULTING FROM THE MOST RECENT INCIDENT. TO THE BEST OF MY KNOWLEDGE, FLEETWOOD HAS NEVER ACKNOWLEDGED THE PROBLEM. NO RECALL HAS EVER BEEN ISSUED. THERE ARE NO SPECIAL PERIODIC MAINTENANCE PROCEDURES IN THE OWNER'S MANUAL NOR HAVE ANY BEEN SENT TO OWNERS. *AK
