The electrical cranking system components, which include the battery, cables, and cranking motor, must be carefully selected to provide the necessary speed to start an engine under the most severe climatic conditions for which the system is intended. Engine cranking loads increase with cold temperatures, therefore, the initial selection of these components needs to consider low-temperature engine torque requirements. To insure an adequate electrical cranking system is obtained, it is important that proper test procedures are used for obtaining the cranking load requirements of the engine.
The Electrical Systems Group is responsible for the maintenance project monitoring and forward planning of all standards projects and the timetables established for those projects by the Technical Committees in the areas of: Power Distribution, Power Systems, Powertrain/Chassis Electronics, Electrical/Electronic Reliability,Multiplexing and Diagnostics,Lighting and Signalling, Intra/Extravehicular Electromagnetic Compatibility as related principally to passenger cars or light trucks and defined by the Motor Vehicle Council.The Group is responsible for organizing or abolishing Technical Committees as needed to undertake and complete the preparation of SAE technical reports in their interest area. This responsibility includes coordination with other Systems Groups to eliminate areas of conflict and duplication and yet ensure that evolving needs are anticipated and met.The Group shall conduct an annual review of its Technical Committees to ensure that new technologies are being addressed within the existing Technical Committees. If no such committee exists, a new committee will be organized. The Group Director shall provide a status report to the Motor Vehicle Council.
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Wild Cards
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Using Quotes
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
