5、09 Superseding J1493 JUL2008 Guarding of Starter System Energization RATIONALE This standard has been revised to clarify that Agricultural Tractors are included in the scope. The 2013 revision to SAE J1116 removed Agricultural Tractors from the scope of that standard however provided a means to cont

REQUIREMENTS 4.1 Guarding of the starter motor solenoid shall prevent the electrical connection of battery jumper cable clamps to the motor terminal (3). Guarding of the starter motor solenoid shall also prevent electrical

15、 connection, by using pliers or a flat rigid conductor such as a screwdriver, between the battery terminal (2) and either the coil terminal (1) or the motor terminal (3). Guarding by location or other means determined by risk assessment to be effective are acceptable protection means. Removable guar

SAE INTERNATIONAL J1493 Revised SEP2013 Page 3 of 3 4.1.1 With the starter motor solenoid guard removed and the wiring attached, if an electrical connection (at the starter motor solenoid) causes the engine to

17、 crank, a fixed barrier on the starter motor solenoid shall prevent electrical connection by using a flat rigid conductor such as a screw driver between either the coil terminal (1) or the motor terminal (3) to the battery terminal (2). 4.2 Other means of preventing hazardous machine movement caused

18、 by activation of the starter motor by bypassing the starter control system are acceptable as alternatives to the fixed barrier or guarding stated in this document. 5.
