Oshkosh Truck Corporation: Electrical System › Wiring
Oshkosh Truck Corporation reported this defect to federal regulators on Jul 19, 1994 and put the number of vehicles at risk at 398. The repair is free for as long as the recall stands.
The defect
DEPENDING ON THE LOCATION AND THE ELECTRICAL DEMAND, A COMBINATION OF CORROSION AND HEAT CAN CAUSE A MOMENTARY BREAK ON EITHER OF TWO ELECTRICAL CIRCUITS AT THE BULKHEAD CONNECTOR (21 OR 29). IF THESE CIRCUITS FAIL, THE IGNITION, PARKING LIGHT, FUEL PUMP, FUSE PANELS AND THE SECONDARY ELECTRICAL BRAKING SYSTEM WILL LOSE POWER.
The risk
LOSS OF POWER TO THE SECONDARY ELECTRICAL BRAKING SYSTEM CAN RESULT IN INCREASED STOPPING DISTANCES AND POSSIBLE VEHICLE ACCIDENT.
The remedy
POWER FROM THE BATTERY WILL BE RUN DIRECTLY TO THE STOP LAMP SWITCH AND THE IGNITION SWITCH. THIS WILL ELIMINATE THE BULKHEAD CONNECTION FOR THE IGNITION CIRCUIT AND BACK-UP BRAKE CIRCUIT AS WELL AS DIVIDING UP THE LOAD ON THE TWO QUESTIONABLE CIRCUITS.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 94V130000.
