There are many grammatical errors in this book, with some affecting the answers to the pre, post, or task questions. Many times the "Hint" has no relevant information to the questions being asked, making the "Hint" completely useless. Sometimes, the "Hint" will be exactly the same for 3 different tasks. There are also errors in the answer key. It also seems that questions were randomly put in where they don't necessarily belong. Finally, if you answer a question based the the exact words that are in the text, you may choose the wrong answer. The answer key will tell you that an answer is wrong but the same answer is correct within the "Hint." This book definitely needed another proof read before publishing. Also, some key air brake system test criteria differ in this book and "Heavy Duty Truck Systems" by Sean Bennett (read my review). With all this said, I have been using this book and Sean Bennett's book to study and have passed 4 out of 4 ASE certification tests for Fall 2011.
This book does cover a lot of information. It explains the correct answers to the questions presented in the book itself. If you have not worked in the Diesel repair field within the last 5 years, you will not grasp a lot of this information. This book is a refresher for working technicians in the field.
Excellent guide to prepare yourself for the ASE H.D. Truck Certification Tests. Provides explanations as to why an answer is correct or not correct. Additionally, provides a synopsis for each section of questions as to the theory behind the system the questions are based on, e.g., a brief explanation of Ohms Law if the questions in the section are about voltage, current and resistance. If you have read and understood textbooks of truck systems and engines, this is the study guide you want to use in preparing for the ASE tests.Here are the two textbooks I used in combination with this study guide.(1) Medium/Heavy Duty Truck Engines, Fuel & Computerized Management Systems, 2Eby Sean Bennett(2) Heavy Duty Truck Systems by Robert Scharff
I have been using this product to study for my ASE certifications and am finding a few of the supposed facts that are not correct in the book. I am not at all happy with these findings.
Could use better explanations on the answers and more text on relating subjects. However, there are plenty of test questions to practive with.
