(Remember we have power supplies for UK and Euro at an additional charge.)

Last add-on trainer:
CAN Bus Troubleshooting Trainer H-200

The CAN Bus troubleshooting trainer, H-200 involves two training topcs. First you learn what the 60 ohm network is, how it works and how it can fail even when you read 60 ohms at DLC Pins 6 and 14. Second, you will learn the proper troubleshooting techniques when a node has a B+ (voltage side) or B- (ground side) problem preventing the node from functioning normally.

(1) Network Wiring Problems
There are 20 hands-on problems troubleshooting the 60 ohm network and how the circuit is not operational yet 60 ohms is measured at Pins 6 and 14 of the DLC. Finding zero, 120 or 240 ohms is also explained and duplicated in the troubleshooting exercises for practice.
These 20 troubleshooting problems are accomplished with an ohmmeter without the need to connect the CAN Bus trainer to the Power Board from The Starter Kit H-111A.

(2) Voltage and Ground Circuit Node Problems

Next the CAN Bus trainer H-200 connects to the Power Board from H-111A as shown at the left to explain CAN Bus circuit troubleshooting concerning node voltage and ground problems that cause technicians the most trouble.

There are 24 problems relating to voltage and ground feeds to the nodes. These node electrical problems are often overlooked.

To troubleshoot these problems the CAN Bus trainer must be connected to the power board from the starter kit H-111A as shown here. This permits measuring voltages in the CAN Bus system relating to voltage and ground circuits to the nodes. Live circuit troubleshooting permits open circuits, voltage drops and shorts to ground to be diagnosed.

Please note there are no voltage or CAN Bus signals on the CAN Bus High(+) or Low(-) network wires.

The CAN Bus trainer H-200, comes with a CAN Bus circuit board, H-PCB200, a student workbook, H-WB200 and Instructor Guid, H-IG200, along with a resistor bag to insert different voltage drop problems in the trainer. The instructor guide has all the instructions you need and answers to troubleshooting questions.

Now you can benefit from Veejer Enterprises' unique style of hands-on troubleshooting training in the privacy & convenience of your home or shop by purchasing our Troubleshooting Trainers, which are fully constructed circuit boards, power supply and step by step troubleshooting training manuals. After you have completed this hands-on troubleshooting training program you can go back again from time to time to review live troubleshooting using the Troubleshooting Trainer Circuit Boards to refresh your troubleshooting skills and stay sharp and share the trainers with other technicians.

You can use the circuit boards over and over, once you have them, and brush up on your electrical troubleshooting skills.

Once you own a Starter Kit, the first step in this hands-on training program, and then buy the add-on troubleshooting kits, (DC Motor Circuit, Relay Circuit and Wire Harness Troubleshooting, CAN Bus Troubleshooting) you can use them to help other technicians learn the methods of auto and truck electrical & electronic circuit troubleshooting.

Learn to read a DMM and recognize the correct voltage, resistance and current readings in auto and truck electrical-electronic circuits with repetitious troubleshooting practice. Depend less and less on sometimes hard to get technical information as you develop hands-on troubleshooting skill using your DMM as taught in this troubleshooting training program.

Proceed at your own pace, step-by-step, and develop vehicle electrical and electronics troubleshooting skills that will place you far ahead of other technicians. After only a couple of hours of hands-on study, you will begin
developing skill in reading schematic diagrams and hands-on troubleshooting with a DMM. You will start using your new found troubleshooting skills in the shop the very next time you encounter an electrical or electronic circuit problem.

With this hands-on training program you will make more money and get electrical jobs done right the first time because you will have the hands-on expertise to troubleshoot vehicle circuits faster and correctly.

You don't learn troubleshooting of auto and truck electrical and electronic circuits by listening to someone talk about it or watching someone else do it.
You have to do it yourself while being guided by expert instructions provided in the manuals that come with each Troubleshooting Trainer.

Veejer Enterprises Inc., has been conducting hands-on Auto/Truck Electrical - Electronics Troubleshooting Workshops since 1986 to train auto, truck and heavy equipment service technicians to successfully troubleshoot vehicle electrical and electronic systems. These workshops have trained professional technicians, trainers and technical school instructors. The success of these troubleshooting workshops is written in the testimonies of our graduates.

Some have written their testimony on our Guest Book.

Many have said they wish they had had this type of electrical training when they started their careers. If they had only known then what this training taught them, they would have made a lot more money over the years and had a lot more fun.

Student Workbooks are designed for home-study or tech school classroom presentation. They guide you with illustrated & detailed circuit testing and troubleshooting instructions to follow at your own pace. As you develop troubleshooting skill with live hands-on application using these specially designed Troubleshooting Trainer Circuit Boards, you will learn how to troubleshoot and find opens, short circuits, shorts to ground, voltage drops and shorts to voltage - anywhere in any circuit - anytime - using just your DMM.
