## Introduction

Congratulations on completing modules 1-6! You should now have a decent understanding of how to read/draw a circuit schematic and how to wire up a circuit based on a schematic. While most maintenance technicians may not be asked to design or wire up a new system, your ability to read a schematic and understand the logical functions that make it work will help you with troubleshooting when the circuit is not functioning correctly.

In Module 7, you will be using Simutech troubleshooting software to learn the process of safely and effectively troubleshooting a non-functioning system. You will learn how to safely detect and locate a short to ground, faulty components, or a loose/open connection in the circuit.

## Objectives

- Safely take necessary multi-meter readings to help troubleshoot a circuit.
- Learn proper Lockout/Tagout procedures to keep you safe when troubleshooting an electrical motor controls system.
- Read a schematic to troubleshoot a malfunctioning circuit.
- Detect and locate an open in a circuit.
- Detect and locate a short to ground in a circuit.
- Detect faulty components in a circuit.
- Safely restore a motor controls circuit to proper functionality.

Note: Do not skip the informational sections and practice faults in the Simutech software. These will help you in establishing a safe and effective troubleshooting process.
