Voltage Regulators for Automotive-Type Generators

2006-01-09
CURRENT
J2669_200601
This SAE Definition Document contains historic voltage regulation methods and test requirements that have not been previously published. The purpose of this document is to recommend a set of definitions and practices for use on current and future 12 V vehicle electric power regulation and control systems in internal combustion engine road vehicles. This document is not intended to include nor exclude regulators used in higher voltage vehicle electrical systems. The term “generator” rather than “alternator” will be used even though these terms may be used interchangeably in practice.

Brake-Stroke Indicator Design Guideline for Cam or Disc Air-Brake Actuators

2018-05-07
CURRENT
J1953_201805
This SAE Recommended Practice shall cover mechanical-brake adjustment limit stroke indicators for actuators with visible exposed pushrods and electrical-brake adjustment limit stroke indicators for all air-brake actuators. This device shall indicate the foundation brake(s) may require adjustment or service when inspected per vehicle manufacturer's procedures. A measurement shall be made to determine actual stroke measurement for any system not factory calibrated. Stroke indication accuracy of an air-brake actuator can be assured only when all of its components are supplied by the original brake actuator manufacturer.
