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.

Note: Specification values are based on the following machine settings unless stated otherwise

Engine Speed Dial "10"
AEC OFF

	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, REHS0354, "Charging System Troubleshooting".
	Electric Starting System Test	12 to 16 V at −23° C (−10° F) to −7° C (19° F)		Refer to Testing and Adjusting, SENR5546, "Electric Starting System - Test".
