Lessons in this Unit
Overview: Using correct go/no-go specifications and a VAT- tester, students will load test vehicle battery, starter and charging systems to determine if those components meet specifications or need service or replacing.
Details: This is a two-hour lesson in which students will learn how to use a SUN VAT- load tester on vehicle battery, starter, and charging systems. The goal: Instruct students on the importance of proper diagnostics for fixed-right first-time and best customer satisfaction.
Understanding the proper use of a load tester such as the VAT- is an important achievement for any automotive student. This lesson combines all three tests the VAT- is capable of performing into one lesson. Additionally, ASE test-preparation tasks will be emphasized during this lesson.
