2016-08932016-10-14. Service bulletin. EQUIPMENT. E-ONE VEHICLES ARE DESIGNED WITH ELECTRICAL CIRCUIT PROTECTION (E.G. FUSES), TO PROVIDE OVERCURRENT PROTECTION DURING SHORT-CIRCUIT CONDITIONS OR MALFUNCTION OF COMPONENTS. FUSES ARE SOMETIMES SHARED AMONGST DIFFERENT CIRCUITS. FOR EXAMPLE, THE CIRCUITS FOR THE PUMP PRIMER MOTOR AND CHASSIS POWER SHARE A COMMON 300AMP FUSE. IF EITHER OF THESE CIRCUITS EXPERIENCES AN ELECTRICAL OVERLOAD, THE FUSE WILL ACT AS DESIGNED TO PROTECT THE USERS AND THE VEHICLE FROM FURTHER DAMAGE. AS SUCH, AN OVERCURRENT CONDITION IN THE PUMP PRIMER CIRCUIT WILL ALSO DISCONNECT MAIN POWER FROM THE CAB AND CHASSIS AND CAUSE THE ENGINE TO SHUT DOWN.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
