Recommended Practice for Identification of Standardized Truck and Tractor Electrical Circuits

2019-01-08
CURRENT
J2191_201901
This SAE document defines a recommended practice for implementing circuit identification for electrical power and signal distribution systems of the Class 8 trucks and tractors. This document provides a description of a supplemental circuit identifier that shall be utilized in conjunction with the original equipment manufacturer’s primary circuit identification as used in wire harnesses but does not include electrical or electronic devices which have pigtails. The supplemental circuit identifier is cross-referenced to a specified subsystem of the power and signal distribution system identified in Section 5.

Recommended Environmental Practices for Electronic Equipment Design in Heavy-Duty Vehicle Applications

2017-03-17
CURRENT
J1455_201703
The scope of this Recommended Practice encompasses the range of environments which influence the performance and reliability of the electronic equipment designed for heavy duty on and off road vehicles, as well as any appropriate stationary applications which also use these vehicle derived components. A few examples of such vehicles are on and off highway trucks, trailers, buses, construction equipment, and agricultural equipment including implements.

Auxiliary Power Unit Electrical Interface Requirements for Class Eight Trucks

2015-12-18
CURRENT
J2891_201512
This SAE Recommended Practice covers the design and application of a 120 VAC single phase engine based auxiliary power unit or GENSET. This document is intended to provide design direction for the single phase nominal 120 VAC as it interfaces within the truck architecture providing power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off.
