How to use a DVOM
Nice video from ifitjams on YouTube on DVOM usage.
Automobile Electrics
So, I think we have some basic idea’s down when repairing your automobile. Let’s talk car electrics. I will break this down in several different post, cause this may take awhile.
An automobile’s electrics can be very easy to understand if you take it in steps. By steps I mean understand how electrics on a car flow, how components work, and reading a good wiring diagram. On most of today’s car a good battery is always need before testing any components circuitry to find the problem. A good volt/ohm meter or DVOM ( digital volt ohm meter) is a must here. Do not use test lights if your first starting out. You can cause more damage to a circuit because of the load a bulb may place on the circuit, especially if it is a airbag circuit. A battery must have a good charge of 12 volts to get good readings. A low or under charged battery can give you false readings when testing a automobile circuit.Get a wiring diagram for your automobile. This is going to save you from a lot of pain and aggravation. You can usually find a good factory diagram some where on the Internet, if not a good basic repair manual will have some kind of diagram. You might have to look a bit more for connectors and plugs with a basic repair manual than a factory diagram. Look at how the circuit work before you start testing and probing. Ground points and power points are always good places to start. If a automobile circuit is not getting the proper power or ground this can can a lot of issues. Look for the easy points to reach first, it might be just that simple.
Then again it might not be. If all the power and grounds are reading as per manufactures specification, then look for connectors in the circuit. See where a wire is going and where it’s coming from. In most causes you will find that a bent male pin of an open ended female pin is not connecting properly. The best way to test this is to pin drag the pins. We will go into circuit testing and fixing later. There is going to be a lot of post about automobile electrics later.
Remember to get a good DVOM and wiring diagram. Start looking at the easy points first, powers and grounds. You may find that the simplest thing caused your car to fail. Take your time where repairing your automobile electrics, better to be careful here and not cause more damage.
