The vehicle battery stores energy at the heart of vehicle electrical systems.
Correct batttery voltage is critical to the operation of many vehicle electronic and rotating electrical vehicle components.
Vehicle batteries are recharged primarily with power generated by alternator or dynamo. Secondary battery charging may be provided by another power source such as photovoltaic solar panels or a mains to battery charger hook up connection. Failure of rotating electrical devices Alternator or Dynamo can be resultant of mechanical, electrical wiring or electronic faults.
Starter motor operation is expected when the ignition key or starter button is activated causing the starter motor to 'crank' the engine.
Modern vehicles may incorporate Stop-Start technology where generator and starter are combined as a Dynastarter lowering both weight and emissions also increasing fuel economy.
Many electrical and electronic components form part of the engine fuel system.
Electric fuel pumps propel fuel from the fuel tank. Pressure and flow is often electronically regulated by
electronic control unit (ecu)
fuel pressure regulator
to meet engine load and driver demand calculated from sensor inputs.
Much diagnostic testing of vehicle computer systems controlling fuel and ignition can be carried out on site with specialised diagnostic equipment.
Vehicle cabin temperature is essential to comfortable transport. Electric windows to provide ventilation are powered up or down by electric motors fitted inside vehicle doors. Typical faults include broken wiring , switch, control module, or electric window motor failure.
Heating or cooling of cabin temperature is provided by heat transfer to or from cabin air using blower fan motor to move air over a heat exchanger such as evaporator or heater matrix. Electrical faults with blower motors, switches, sensors, and wiring can cause problems.
Alarms and immobilisers enhance vehicle security to prevent vehicle starting and reduce risk of vehicle theft but can also cause nuisance and breakdown. Typical faults include wiring, control module, coding, environmental factors causing false activation.
Failed aftermarket alarms and immobilisers can often be removed by an autoelectrician, however vehicle insurance company may require notification
Brake electronics include antilock braking system, brake pad warning, brake fluid level warning. Typical faults can result from mechanical , hydraulic and electical failure causing warning lamps to illuminate. Braking electronics may include ABS, Electronic Park Brake, Handbrake Assist, Low Air warning Guages.
Fleet tracking telematics satnav gps may communicate data from vehicle to receiver. Recent industry warnings have questioned security of telematics devices linked to vehicle control electronics where integrity of computer systems may be compromised wirelessly.
CANbus refers to serial data communication between electronic modules in the vehicle computer network. CANbus faults can include shorted wiring, open circuit breaks, signal processing faults at electronic control modules. Computer diagnostics may be required to investigate fault codes followed by more indepth testing of wiring with multimeter or oscilloscope.
We provide a wide range of mobile autoelectrician services to the fleet transport industry including installation wiring and rotating electrical components.

Robust classic vehicle technology is often rendered redundant in pursuit of vehicle manufacturer design engineers innovation to gain safety, comfort, performance and efficiency whilst reducing pollutants. There is much to be said for simplicity however classic vehicle wiring has its own quirks sometimes including positive earth wiring systems with seperate voltage or current regulator and dynamo charging systems, distributor and contact breaker points ignition requiring timing and setting of contact breaker points gap. Many older uk manufactured vehicles use the Lucas colour coded wiring system.
Increased vehicle complexity in modern vehicles has relied upon computer technology to produce and manage data produced by control systems questioning whether product redundancy has also been introduced to increase new vehicle sales.
Vehicles are subject to many different operating environments affecting temperature, vibration, humidity, mechanical and electrical stress which can lead to premature failure of these electrical and electronic systems designed to control engine ,body, steering , braking and other mechanical systems.
