Introduction

Inspections are the most basic form of condition monitoring. Inspections are easy to do and surprisingly effective at helping you spot equipment health issues. Proactive monitoring and analysis of equipment information will allow Dealers to intervene effectively before problems occur.

Note: Before adjusting product settings to comply with listed baseline TA2 values, consult SIS for the latest specification values.

    Inspect Battery Cables     Cables between the battery, the starter, and the engine ground must be the correct size. Wires and cables must be free of corrosion. Wires and cables must have cable support clamps in order to prevent stress on battery connections (terminals).            
    Battery Test     12.4 VDC or more         Refer to Special Instruction, SEHS7633, "Battery Test Procedure".    
    Charging System Test     18 VDC to 32 VDC         Refer to Special Instruction, UENR0950, "Charging System - Test".    
    Electric Starting System Test     6 to 8 V at −23° C (−10° F) to
