Overview

Heavy Vehicle Essential Test Procedures:HV56

Need electrical diagnosis skills?
Get confident in testing and find the faults!

All technicians require electrical system know how and fault finding skills to work on modern vehicle systems. The content of this course is essential knowledge for the development of a technician’s diagnostic capability. The overall learning goal is to provide delegates with a working knowledge of standard electrical test procedures and how they are applied correctly. These tests allow delegates to perform electrical confirmation checks with confidence when carrying out diagnostic routines.

Course content
• Electrical values and their measurement for test purposes
• Test methods for circuit continuity, insulation and resistance
• The properties and testing of series and parallel circuits
• The application and use of voltage drop measurement tests
• Preliminary review of the oscilloscope
• Waveform display with control adjustments and settings
• Connections and test methods

Prerequisites
We recommend that delegates are familiar with the basic operation of a typical digital multi meter and oscilloscopes.

Attainment
On successful completion of HV56, delegates will be able to:
• Use electrical test equipment correctly on vehicle system circuits.
• Carry out test procedures using voltage resistance and current measurement
• Carry out test procedures using voltage drop method to indicate circuit faults
• Connect a typical automotive oscilloscope to a vehicle system component or wiring to display a signal wave form
• Adjust the common oscilloscope controls and settings to manipulate the signal displayed so that it can be analysed
