The next troubleshooting trainer continues to develop electrical troubleshooting skills as techs learn to troubleshoot brushless DC Motor 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.

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 Workbook, Part Number H-WB113, 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 about 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, 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. 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. The 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.
