Welcome! Here you're gonna' find HOW TO TEST articles with tests that are easy, fast, and simple.They are real world tests with step by step instructions. No baloney and/or useless theory. You'll find articles on:
Wondering How to test a MAF SENSOR or an IGNITION CONTROL MODULE, you'll find plenty of specific articles that will take you step by step thru' the test. Whether it's FORD or a HONDA or any of the GENERAL MOTORS makes, you'll find them here and others.
I call them Fast Tests. Why? -'cause they're easy, simple and fast ON CAR TESTS. No expensive equipment to use or buy. You'll be using a multimeter, or an oscilloscope (tho' a scope is NOT a must to use the info in this Site) or something as simple as an LED light.
What's the purpose of this Site?- To make your life easier by offering you tested information from someone who is actually doing it (have I mentioned that it's also FREE). These articles are not tutorials on the basics of diagnostics. Nor useless info after which, at the end of the article, the author tells you to take it to a shop. These articles are real world examples of the actual testing process to arrive at the specific conclusion: YES, the part is bad or NO, the part is not bad (for a specific make and model).
This is by no means a complete work, but you'll find dozens of specific Articles organized by make, model and year. I have decided to tackle the tests that seem to give folks a lot of trouble: Ignition Control Module (ICM) Tests, Mass Air Flow (MAF) Sensor Tests, Ignition Coil Pack Tests, Coil-on-Plug (COP) Ignition Coil Tests, Alternator and Starter Tests and EGR Valve Tests. This Site will be another tool in your toolbox and a source of information that you'll keep coming back to. If you don't find an article for your present need, take a look anyway. You may find something to inspire your next diagnostic move.
This site is bi-lingual. I have translated all of the articles to Spanish (North American Spanish). All you have to do is click "Español" on the top Tab bar and that same article will appear in Spanish. Lastly, all of the Articles are based on my own experience and ideas. I've spent many, many hours making sure the info is correct and I hope they help. But nothing in life is perfect. Having said that, I'm (here goes the end of the disclaimer) not responsible for how you use, apply or abuse this information.
