Hello Mark greetings from Mexico city, I hope you can help me since I have a question about this video, Actually I go to school to get a degree as an auto technician and well today I had to give a class about DIS and I showed this video to the class and they love it but unfortunately my teacher did not agree about the spark traveling trough the mono block and then being picked up by the second spark plug from the cylinder that controls the same DIS, how can be this possible?

@sangreazteca69 Hello, I first want insure you everything in this and all our videos is fact. I do not blame your teacher, I am sure he is very good, it can be hard to understand this system. On a DIS coil the primary and secondary windings do not touch each other. Remember, electricity will always return to it's source. If the windings do not touch each other the source for the high secondary current is the secondary winding. You can prove this by removing the spark plug wires from a coil and

@sangreazteca69 cranking the engine over. You will see the spark jumping from one tower to the other and not to ground. I hope this helps you. If you need any further information please let me know. Congratulations on your English, it is very good. I wish my Spanish was half that good.

On a DIS system that fires two plugs at the same time, you need to use a double platinum plug instead of a platinum plug. Otherwise, half the plugs will experience premature wear.

@LarryLane07 Larry you absolutely correct. Thank you for bringing up this important point.

@dmorley100 You are absolutely correct. I could not have said it better myself. After all these years it is still a black art in many ways. This is why my articles and videos focus on the the function and testing of systems. If you have a good understanding of how the system functions you are well on your way to making an accurate diagnosis. But as hard as I try; are there times when I make the wrong diagnosis? Yes it still happens from time to time.

Thank you for the great post.

@lawnside82 Glad you liked the video. Keep watching we have many more coming.

@markjhicks2 What makes it real bad is that ain't just technicians who suffer from a lack of education. Service writers are bad about it too. They don't realize how much time and thought it takes to properly diagnose problems. They expect it to happen almost instantenously and that the scanner'll just magically tells you exactly what's wrong with the car. If that was really the way it worked, wouldn't either one of us have a job right now.

wow i learned alot!! tanks for posting this video! makes me want to replace my coil pack plugs and wires! asap!

@dmorley100 There are a lot of misconceptions in this business. Unfortunetly, it is a much bigger problem then a garage actually ripping someone off. But, the public does not think that way. When a technician misdiagnosis a problem many customers will immediately think he is trying to steal from them. When in fact it is a problem of education. Sad but it is the bitter truth.

Thank you for the reply,
