The hazard
On certain buses, the Megafuse junction box is located in an area exposed to excessive road splash and spray. In some applications the cable connections may corrode rapidly. If undetected, extreme corrosion may cause a power cable to become separated from the power source resulting in an unexpected engine shutdown or loss of vehicle lighting and windshield wipers. Unexpected engine shutdown or a loss of vehicle lighting and windshield wipers in certain traffic conditions could increase the potential of a vehicle crash. Correction: Dealers will replace the Megafuse junction block and electrical box.
