NHTSA recall 05V153000
Electrical system
Road Rescue Ambulance
The defect
On certain ambulances equipped with the "smart display" electrical system containing field-effect transistor (fet) output boards, the power distribution panel for the smart display are equipped with type 1 circuit protection. this allows the board to shut down if an over-heating condition or an over current condition IS detected. as the board cools down, it comes back on, allowing the board to continually cycle leading to possible failure.
The risk
The boards can possibly overheat or melt down, which could cause a fire.
The remedy
Dealers will install a new transistor fet board that contains type 2 circuit protection free of charge. the recall began on september 6, 2005. owners may contact road rescue at 1-800-328-3804.
