The next troubleshooting trainer continues to develop electrical troubleshooting
skills as techs learn to troubleshoot brush less DC Motor (new technology) circuits
and brush-type DC Motors (starters and blower motors).
This add-on module consists
of a DC Motor Circuit Board Troubleshooting Trainer, Part
Number H-PCB03 (H-113), which is plugged into the Power Board from
the Starter Kit (H-111A), as shown here.
A dedicated Home-Study Student Workbook, Part Number H-WB113, walks Techs through the theory,
operation and troubleshooting techniques of brush less DC Motor
Circuits. Material also discusses testing common brush-type DC Motors used
as starter motors and a/c-heater blower motor circuits using a Current Clamp.
Students learn characteristics of analog ohmmeters, their differences and operating characteristics to understand which ohmmeter could be used to test a brush less DC motor before ordering a new one. Students also learn to use the Diode Test feature of a DMM to test a brush less DC motor.
30 pages of self-paced step-by-step instruction, Techs begin
troubleshooting 37 individual electrical problems in the DC
Motor circuit which are inserted one at a time on the bottom of the circuit boards following
instructions in the Instructor Guide, H-IG113.
The DC Motor circuit is described
as an engine-cooling fan circuit to add realism to the
37 troubleshooting problems with actual cooling fan symptoms, such as engine run hot (weak cooling fan operation). Circuit problems inserted are
open circuits, voltage drop problems on either the voltage-side
or the ground-side of the circuit, short-to-ground and short-to-voltage problems with some added enhancements over the
original Starter Kit troubleshooting problems.
Learn to quickly troubleshoot and identify
advanced ground-side problems. Follow these troubleshooting procedures
and breeze through ground-side problems in any vehicle circuit.
One problem simulates a battery drain problem because
the cooling-fan runs all the time when the ignition switch (on
the Power Board) is switched OFF. The realism added to the troubleshooting
problems helps to maintain interest and relate the troubleshooting
exercises to real world problems.
After mastering the first 37
DC Motor circuit problems there are 5 Advanced Electrical Problems
to present additional challenge to Techs who are ready for more
of an advance test of their troubleshooting ability. That's a total of
42 individual electrical troubleshooting problems.
