Relay Circuit
Troubleshooting Trainer
Module H-115

Troubleshooting Relays can be a difficult task given all the possibilities of how a relay circuit can fail. What do you do after replacing a relay and it does not fix the relay circuit problem? Then it's time to start troubleshooting the relay circuit using troubleshooting training presented in this training program. Let us show you how!


Add-on Troubleshooting Trainer
to the "Starter Kit, H-111A"

The Relay Circuit Troubleshooting Trainer, H-PCB05 shown at the left, is connected to the Starter Kit's Power Board and Power Supply (from H-111A). A technician can now learn all about relay circuits and practice troubleshooting 75 live relay circuit problems.

Multiple hands-on practice exercises are embedded in the Student Workbook H-WB115 text (over 110 pages) with extensive instructions covering relay operation, characteristics of relay circuits, spike suppression diodes/resistors and relay circuit troubleshooting techniques.

Learn how relays are used in vehicle circuits but more importantly how relay circuits fail and the troubleshooting techniques to find any relay circuit problem when a new relay didn't fix the problem.

This program contains extensive step-by-step instruction and hands-on exercises. Techs learn to analyze the ways relay circuits fail, how to measure voltage, voltage drops, resistance and current in relay circuits and to identify relay circuit problems. How spike suppression diodes connected across a relay coil work is thoroughly discussed and what happens when the diode fails. Then spike suppression diode testing with an analog ohmmeter, a digital ohmmeter and the Diode Test feature of a DMM is discussed with hands-on exercises to follow along step-by-step. Learn why the DMM's Diode Test feature doesn't always work to test spike suppression diodes.

All this is followed by hands-on practice in relay circuit troubleshooting technique as techs practice troubleshooting 75 individual live relay circuit problems, one at a time, to develop electrical troubleshooting skill and self-confidence. Each troubleshooting problem addresses the relay as a fuel pump relay and the lamp simulates fuel pump operation. A scenario (customer complaint) accompanies each problem relating to a fuel pressure issue that would result from the problem inserted into the circuit boards to add realism to the live troubleshooting exercises. This helps techs to consider an actual problem with fuel pressure and relating it to a specific relay circuit failure, in this case a fuel pump relay.

The Relay Instructor Guide, H-IG115, provides answers to all review exercises and complete instructions for inserting relay circuit problems in Relay Circuit Troubleshooting Trainer. Answers to each troubleshooting problem are also included so you can teach yourself.

Techs troubleshoot from the top side of the PCB using test points provided on the Troubleshooting Trainers and their own DMM. Students evaluate their troubleshooting progress by comparing their review exercises and troubleshooting procedures with the Instructor Guide notes.
