NITA Auto Electrician Trade Test study guide
NITA Auto Electrician Trade Test · Work through your exam, one topic at a time.
The NITA Auto Electrician Trade Test is a Kenyan trade certification assessment for people who diagnose, service and repair the electrical and electronic systems of motor vehicles. Candidates are typically apprentices, technical-college leavers, garage hands seeking formal recognition, or experienced auto electricians who need a certificate to support employment, licensing or further training. The NITA Auto Electrician Trade Test study guide has 11 sections and about 3,330 words.
01Electrical Principles and Circuit Fundamentals
Electrical Principles and Circuit Fundamentals is the foundation domain. The trade test checks whether you can calculate voltage, current, resistance and power in vehicle circuits, recognise series and parallel networks, and explain short, open and high-resistance faults.
353 words, about 2 min02Batteries
Batteries covers lead-acid construction, capacity and cold-cranking ratings, state of charge, charging methods, failure modes and safety. The test expects you to choose the right test and interpret results, rather than simply declaring a battery flat.
298 words, about 1 min03Charging and Starting Systems
Charging and Starting Systems tests alternator operation, rectification and regulation, starter motor and solenoid operation, and the voltage-drop checks used to find high-resistance cables and grounds. You must be able to explain a charging warning lamp and a no-crank complaint.
312 words, about 2 min04Lighting, Signalling and Auxiliary Electrical Systems
Lighting, Signalling and Auxiliary Electrical Systems covers headlamps, indicators, hazards, brake and reverse lamps, horns, wipers and the relays and fuses that support them. The test checks circuit operation, switching, protection and legal aim.
288 words, about 1 min05Ignition Systems and Engine Electrical Management
Ignition Systems and Engine Electrical Management covers coil operation, distributor and distributorless systems, coil-on-plug, dwell and timing, and the sensor inputs the ECU uses to control spark and engine operation. You need to understand primary and secondary circuits and how management inputs affect them.
309 words, about 2 min06Wiring, Harnessing, Connectors and Circuit Protection
Wiring, Harnessing, Connectors and Circuit Protection tests cable selection, voltage drop, fuses, relays, terminal repair and loom routing. You must choose and repair wiring so it carries current safely and survives vibration, heat and abrasion.
329 words, about 2 min07Diagnostic Testing, Fault Finding and Measuring Instruments
Diagnostic Testing, Fault Finding and Measuring Instruments tests systematic diagnosis using a multimeter, test lamp, oscilloscope and scan tool. You must verify the complaint, test the circuit under load and interpret codes and live data without unnecessary parts replacement.
308 words, about 2 min08Electronic Control Units, Sensors and Actuators
Electronic Control Units, Sensors and Actuators covers ECU inputs and outputs, reference voltages, sensor signal types and actuator control. The test checks whether you can trace a fault from a sensor signal through the ECU to an actuator without guessing.
296 words, about 1 min09Electrical Machines, Motors and Motor Controls in Vehicles
Electrical Machines, Motors and Motor Controls in Vehicles covers DC motors, permanent-magnet and series motors, stepper and brushless motors, and the relays, H-bridges and PWM controllers used in vehicles. The test checks motor behaviour, current draw and safe control.
275 words, about 1 min10Workshop Safety, Tools, Equipment and Environmental Practice
Workshop Safety, Tools, Equipment and Environmental Practice tests safe battery work, electrical isolation, tool use and responsible waste handling. The exam expects practical safety decisions, not slogans.
274 words, about 1 min11Technical Drawing, Schematics and Trade Calculations
Technical Drawing, Schematics and Trade Calculations tests your ability to read wiring diagrams and symbols, follow DIN terminal numbering, and calculate current, voltage drop, cable size and fuse rating. You must use the diagram key and show the calculation, not guess.
