The problem
THE CB-49 CIRCUIT BREAKER TRIPS UNDER NORMAL LOAD CONDITIONS BECAUSE THE ELECTRICAL LOAD APPLIED IS CLOSE TO THE BREAKER RATING AND THE TEMPERATURE IN THE ENGINE COMPARTMENT AFFECTS THE PRECISION OF THE BREAKER. THE TRIPPED BREAKER RESULTS IN LOSS OF STOPLIGHT OPERATION.
Risk
WITHOUT STOPLIGHT OPERATION, THERE IS NO WARNING TOTRAFFIC THAT THE VEHICLE IS SLOWING OR STOPPING, WHICH MAY RESULT IN ANACCIDENT.
What owners should do
A CIRCUIT BREAKER MODIFICATION WILL BE PERFORMED USING A DIFFERENT CIRCUIT BREAKER WHICH IS MORE RESISTANT TO HEAT.
