Auto Electrics


Auto electricians are responsible for installing, maintaining, modifying and repairing the electrical wiring and fixtures on cars and trucks. Highly skilled, these electricians are required to have a deep knowledge of both automobiles and electrical systems. Technicians who work on newer-model cars must also understand the computers and circuit boards that regulate many of the automobiles’ functions. Mark Anderson is a Highly credentialed and respected Auto Electrician in the Industry.

You should regularly check all your lights and bulbs. As sometimes they can fail in combinations, it's best to ask someone to look at the front and rear while you test them. Check your brake lights and indicators with the headlights on and off, as sometimes a bad earth can cause a fault if both lights are on together.

Sometimes you may be dazzled by oncoming vehicles at night that appear to be on main beam. Often they are not, it's just the alignment that's incorrect. Make sure yours are adjusted correctly, dazzling can cause accidents.

Few people realise how important it is to carry spare bulbs, until one fails in the middle of a long journey. These are easily bought, stowed in the car and replaced - a small price to pay for peace of mind.

Consult the handbook if you are having problems. If the light or lights still do not work after the bulb has been replaced, there may be a fuse fault. Look in the fuse box and find the appropriate fuse; replace if necessary.

An automotive battery is a type of rechargeable battery that supplies electric energy to an automobile.

An automotive SLI battery (starting, lighting, ignition) powers the starter motor the lights, and the ignition system of a vehicle's engine.

Automotive SLI batteries are usually lead-acid type, and are made of six galvanic cells in series to provide a 12-volt system. Each cell provides 2.1 volts for a total of 12.6 volts at full charge. Heavy vehicles, such as highway trucks or tractors, often equipped with diesel engines, may have two batteries in series for a 24-volt system or may have parallel strings of batteries.

Lead-acid batteries are made up of plates of lead and separate plates of lead dioxide which are submerged into an electrolyte solution of about 38% sulfuric acid and 62% water. This causes a chemical reaction that releases electrons, allowing them to flow through conductors to produce electricity. As the battery discharges, the acid of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate. When the battery is recharged, the chemical reaction is reversed: the lead sulfate reforms into lead dioxide and lead. With the plates restored to their original condition, the process may now be repeated.

Battery recycling of automotive batteries reduces the need for resources required for manufacture of new batteries, diverts toxic lead from landfills, and prevents risk of improper disposal.

Since the battery is the source of electricity for a vehicle, it is no surprise that it is a common cause for many automotive electrical problems. Usually the issue is a dead battery, caused when the battery can no longer hold a charge. Sometimes a faulty component of the vehicle can cause a dead battery, other times it can be a result of leaving a component like the headlights or stereo on for an extended period of time. This problem can usually be remedied easily with a jump start or a battery charge. A car battery can also become damaged or simply too old and in need of replacement

Another source of a common auto electrical problem is the vehicles Alternator.

​While the vehicle is running, the Alternator is recharging the battery. Once the Alternator breaks, the battery is quickly drained and the vehicle looses power. Sometimes the Alternator belt can wear out and become cracked leading to a similar malfunction where the battery easily becomes discharged.

Your engine runs on air, fuel and spark. The spark is the centre of it all, and for that we need electricity. Your battery supplies electricity, but only enough to get you a few miles down the road. We need more. That's where the alternator comes in. The alternator continually charges the battery so that we never have to worry about that whole "running out of juice" problem. Your battery is 12 volts, but to keep the battery 100% charged and run all of your car's electrical components at the same time, the alternator has an output of between 13.5 and 14.8 volts.

The alternator has three main components: The Stator, Rotor, Diode and a voltage regulator. When the alternator belt or V-belt spins the pulley on the alternator, the rotor inside the alternator spins ... fast. The rotor is basically a magnet or group of magnets that spin, with all that speed, inside a nest of copper wires. These wires are called the stator. I won't go into all of the details about why a magnet spinning within a bundle of copper produces electricity, but it does. The next step in the chain is a diode assembly that changes the electricity from AC to DC current that your battery can use. There is a final step in the chain, the voltage regulator. In modern alternators, this is a built-in component. Back in the day voltage regulators were big black boxes that had to be bolted somewhere under the hood and wired into the system.

The electric automobile self starter or best known as the starter is the device chiefly responsible for carrying out the processes involved in starting vehicles up.

The car starter works by harnessing the power of the automotive battery. Once the key is inserted into the ignition switch and then turned to the start position, a tiny amount of current flow through the neutral safety switch and into the starter relay or starter solenoid. The starter motor then cranks the engine to enable the piston to create a suction drawing in the fuel and air mixture into the cylinder. The engine will then start as the spark created by the ignition system will ignite this mixture.

Turning on the ignition switch allows a small amount of power from the battery to flow to the solenoid above the starter.

Turning on the ignition switch allows a small amount of power from the battery to flow to the solenoid above the starter. When the low-current power from the starting battery is applied to the solenoid, oftentimes with a key-operated switch, it releases a small pinion gear on the starter motor's shaft and meshes it with the ring gear on the flywheel of the engine.

The solenoid is also responsible for closing out high-current contacts for the starter motor and it then starts to run. Once the engine starts, a key-operated switch is activated and a spring in the solenoid assembly pulls the pinion gear away from the ring gear which then causes the starter motor to stop. Modern auto starter motors are equipped with a "bendix," a gear and integral freewheel, or overrunning clutch, thereby allowing the flywheel to automatically disengage the pinion gear from the flywheel when the engine starts.
