Using Electrical Wiring Diagrams for Heavy Trucks Effectively

Electrical Wiring Diagrams for Heavy TrucksMany do not give thought to the complex under belly of heavy duty trucks and equipment. In fact, Most would be surprised if they looked at electrical wiring diagrams for heavy trucks and would soon realize the complexity of the wiring system. Some are more intricate than the basic electrical wiring of a house. With the exception of an electrical meter base (a truck does not have one like your house); many heavy duty trucks and equipment operate on the same circuitry system principle as your home. The other exception is it is all done on the move with a single engine and battery power source. All of this makes for a labyrinth of wiring.

Reasons Why Electrical Wiring Diagrams for Heavy Trucks are Important

Every single light and function in heavy duty equipment must be powered by electricity. This electrical circuitry is more complicated in commercial equipment (versus automobile electrical wiring diagrams) because the equipment usually provides more than just moving people from one place to another. Often the heavy duty equipment is doing a lot more work, sometimes employing attachments as well, that all need to be powered. The battery and alternator keep the items running by converting electrical currents to power.

Having The Right Information And Equipment

  • If you are an operator, you will probably want to be familiar with electrical wiring diagrams for heavy trucks and equipment you operate. The schematic drawings will help you trouble shoot and DIY basic problems yourself. You will also need the information so that you will know how to hook up any attached equipment you might need. Equipment might include trailers, farming implements, blades and hydraulics (such as a dump bed).
  • You may drive as a fleet operator and have available mechanics to check and fix problems. For your safety, it is best to double check your truck or equipment. Brakes and acceleration are controlled by the electrical system; any missed problems could be fatal. Double checking is certainly better than having any fatalities.
  • Part of driving heavy trucks and equipment is making sure the machine does not pose a hazard to public safety. The operator is responsible for any safety violations such as malfunctioning lighting on the vehicle and attachments. If you are stopped by law enforcement and found to have a problem; you are responsible. You can be given a ticket and if serious enough of a violation; made to park the truck until fixed. If you are familiar with the schematics of the truck you can get it fixed much more quickly.

Where to Find Electrical Wiring Diagrams for Heavy Trucks and Equipment

If you do not have access to the diagram you need; you can:

  • Check with your supervisor if it is a company truck.
  • Ask a mechanic. A mechanic keeps a library of books and manuals that contain electrical wiring diagrams for heavy trucks. He/she may have the one you need.
  • Look online. Several websites exist that have a link to the diagram you are looking for. Some provide a link to the manufacturer of the truck or equipment.

Calling the manufacturer is not always practical. With the internet and computers; you are much more likely to download the diagrams via electronics that get someone to mail you a paper copy. You may eventually get one, but you could have gotten the manual and fixed the problem by the time it arrives in the regular mail.

Understanding How to Add an Outlet to Your VehicleElectrical Wiring Diagrams for Heavy Trucks

When you add a power outlet to your vehicle; charging electrical items such as a cell phone, digital camera or laptop is easy while on the road. The outlet can be used while the vehicle is moving or sitting still with the motor off. In order to reap the benefits of a power source, you need to have some understanding about how different types of power current operate and your automobile electrical wiring diagrams. Automobile electrical wiring diagrams and electrical wiring diagrams for heavy trucks can usually be found in the owner’s manual of your car. If you do not have the owner’s manual; you can look online for it or contact the manufacturer of the vehicle.

Determining Whether Your Car Will Handle and Outlet

The first thing you need to determine is whether or not your car has a cigarette lighter. Many new cars have the plug in opening (usually pre-wired); check your automobile electrical wiring diagrams for confirmation of this. If for some reason, your car does not have an existing lighter plug in to utilize as a power source, it may be very difficult to add an outlet. You will need additional electrical outlet diagrams and some experience (or a professional) to tackle the project. You can seriously damage a car’s electrical system if you do not do the outlet wiring correctly. You might also wind up with a car that does not run at all if there is an error.

The steps below are very simple instructions for adding an electrical plug (like those in the wall of your home) to use with mainly digital equipment. Making the assumption that you have a functioning cigarette lighter plug.

  • Step One – Decide what the power needs are for the equipment you will plug in. You will need to know how many watts a piece of equipment draws through the wire. Most power converter outlet boxes will be between 80-120 watts. Here is a list of common items and their average wattage consumption. Some models will be more some a little less. You should get a good idea of how large a convertor you will need.
  1. Laptop-45 watts
  2. Cell phone charger-10 watts
  3. DVD player-30 watts
  4. Camera-10 watts
  • Step Two – Now that you know the maximum amount of wattage you will need, you can purchase a convertor. You can usually find one in the automotive department. Typically it will be called an auto AC/DC power converter outlet. Buy a convertor that is large enough to meet your needs. Not buying one large enough could lead to damage to your electrical apparatus or car battery.
  • Step Three –Before you install the outlet convertor, check the instructions for wiring requirements with you automobile electrical wiring diagrams for compatibility. Once you are sure, you simply plug it into the cigarette lighter plug and voile’, you have an electrical plug in for your car.

Any lighting (spotlights, etc) will usually have the wattage on the box, in the user’s manual or on the side of the light. Electrical gadgets generally include the wattage in the instructions.

Most products will either have a tag or the wattage stamped on it somewhere. It is usually given as Amps. You can easily convert Amps to Watts by using the formula (Amps x Volts=Watts). The volts will be 120 (this is standard). Take the number of Amps x 120 and you will get the wattage of the product.
