Abstract: The system provides for controlling the connection of electrical power sources to electrical loads installed on a motor vehicle and limiting exposure of personnel to relatively high electrical voltages from the electrical power sources. The system includes a serial communication bus and power cables routed through the motor vehicle. At least a first connector is provided through which the serial communication bus and a power cable are routed allowing temporary severing of the serial communication bus and the power cable. The power cable includes a circuit interrupter which isolates the connector from the electrical power source in response to certain conditions on the serial communication bus, including, but not limited to, the cessation of data traffic on the serial communication bus.

Abstract: A tandem rear axle (28) suspended from a chassis frame (12) rearward of front steerable wheels (22, 24) has a first drive axle (30) with a driven wheel (32) on the right side and a driven wheel (34) on the left side and a second drive axle (36) rearward of the first drive axle and having a driven wheel (38) on the right side and a driven wheel (40) on the left side. A drivetrain couples a combustion engine (26) to the first drive axle for driving its driven wheels. A prime mover (52, 68, 70, 74) other than the combustion engine drives the driven wheels of the second drive axle.

Abstract: A motor vehicle electrical power system provides monitoring of the connection between a vehicle battery and a direct current power source for charging the battery. A voltage transient detector determines if voltage levels on the connection between the vehicle battery and the direct current power supply exceed a minimum threshold. Additionally, a timer or low pass filter passes only voltage transients of a minimum duration. Responsive to detection of a voltage transient exceeding the minimum threshold and duration a load dump event is signaled indicating a possible transient interruption of the connection between the vehicle battery and the direct current power source has occurred.
