Troubleshooting manuals
Troubleshooting manuals and Two golden rules that mechanics follow. Mark here with some advice on finding and reading repair diagrams. The first challenge you will face is finding the right diagnostic chart for the vehicle that you're working on. Once you find the correct procedure or tree chart then you have to read it, analyze it and understand it fully to be successful. When it comes to online automotive repair diagrams all data is one of the most respected professional computer based car repair software programs ever developed for mechanics and shops. They created a DIY repair product to allow driveway warriors access to this high quality information.
I have purchased this to use on my own truck a 2004 Chevy Blazer. I put together a quick home made video to show you some of the key features of the online Chevrolet repair manual. This demo lets you see what it looks like on the other side of the login before you buy it! Troubleshooting manuals rule number one
The first step is to sit down and read the diagram until you fully understand how the circuits work. This may take a little while but will pay big dividends during the diagnosis of your specific car problem.Do not be concerned with how long this first step takes it is not a sign of weakness or lack of intelligence. If you take some time to understand the circuit and the flow of the repair diagram you will be able to pick out the malfunction much quicker. Spend some time now and save more time later is how it works out. Most auto repair manuals are laid out or drawn as a straight line, better known as a ladder repair diagram. Just about every troubleshooting manual uses this standardized approach. This allows you to apply logic and proceed in an organized fashion.
Another advantage of doing this is that you can make notes on your sketch of the circuit so you don't ruin the service manual graphic. When you take a pen to paper it helps your mind rap around the operation of the circuit easier than if you just stare at a picture of the repair diagrams. This is just my opinion and every body is different in how they learn things and retain information. Troubleshooting manual rule number two
When you are tracing an electrical circuit using an automotive repair diagram you always want to work from the load back to the battery. Find the load component first for example light, horn, coil, solenoid or actuator, then find its ground, and then find the battery. Trying to read a schematic from positive to negative doesn't work well. Always try to work from your load back toward the battery. This rule is important because it gives you a correct direction of diagnosis. When you are studying troubleshooting manuals and repair diagrams, you will note that there is usually only one load component per circuit. This simple fact creates a straightforward diagnosis with better results. If you are looking at a large repair diagram, and you see more than one load, example starter, light bulb, backup alarm. You will know that each of these items or loads are on separate circuits and usually run to separate fuses.
In most cases you will find electrical failures isolated to one circuit. If you find yourself jumping around into multiple circuits for diagnosis, it's time to take a step back and return to rule number one. And go back to study the diagram more thoroughly. Just like most things in life the more you use a troubleshooting manual, the easier the repair and diagnosis becomes. This is most definitely one case of practice makes perfect. Studying repair diagrams and learning how to use troubleshooting manuals is an extremely valuable skill. Not just for use in the automotive world, but also construction, equipment repairs, plumbing, and computer system diagnosis all use a standardized ladder repair diagrams.
