This add-on troubleshooting trainer to the Starter
Kit continues developing auto/truck electrical/electronics troubleshooting
skills as techs learn to troubleshoot brushless DC Motor circuits
and brush-type DC Motors. The DC Motor Troubleshooting Trainer
part number is H-113.
This new add-on module consists
of a DC Motor Circuit Board Troubleshooting Trainer, Part
Number H-PCB03, which is plugged into the Power Board from
the Starter Kit, as shown to the left. Once the DC Motor circuit
board is connected to the Power Board Techs are ready to immediately
explore with hands-on exercises the testing and troubleshooting
of live DC Motor circuits. A dedicated Home-Study Student
Manual, Part Number H-SM03, walks Techs through the theory,
operation and troubleshooting techniques of brushless DC Motor
Circuits and discusses testing common brush-type DC Motors used
as starter motors and a/c-heater blower motor circuits. After
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 following
instructions in the Instructor Guide, IG03.
The DC Motor circuit is described
as an engine-cooling fan circuit to add realism to the
37 troubleshooting problems. The circuit problems inserted are
open circuits, voltage drop problems on either the voltage-side
or the ground-side of the circuit and short-to-ground, and NEW
short-to-voltage problems with some added enhancements over the
original Starter Kit. Several problems deal with more advanced
ground-side failures. Learn to quickly troubleshoot and identify
advanced ground-side problems. Follow these troubleshooting procedures
and breeze through ground-side problems in any vehicle.
The DC Motor Circuit's 37 troubleshooting
problems are described as "engine running too hot"
or "gradually overheating" due to a failure of the
cooling fan (DC Motor acting as cooling fan), that is visually
obvious from the performance of the DC Motor fan in each problem.
Some problems simulate battery drain problems because
the cooling-fan runs all the time when the ignition switch (on
the Power Board) is switched OFF. This realism added to the troubleshooting
problems helps to maintain interest and relate the troubleshooting
problems to real world problems. After mastering the first 37
DC Motor circuit problems there are 5 advanced problems
to present additional challenge to Techs who are ready for more
of a test of their troubleshooting ability. That's a total of
42 individual electrical troubleshooting problems. To
