Call a mechanic for mechanical parts — the engine, brakes, suspension, steering, cooling system and servicing — and an auto electrician for anything electrical: batteries, alternators, starter motors, wiring, lights, sensors, warning lights and computer programming. Many problems, like a car that won’t start, sit across both trades, which is why an electro-mechanical business like BOSS 1 handles both in one visit.

What a mechanic fixes
- Engine repairs, oil leaks and servicing
- Brakes: pads, discs, calipers and fluid
- Suspension, steering and wheel bearings
- Cooling system: radiators, hoses and water pumps
- Belts, clutches and drivetrain
What an auto electrician fixes
- Batteries, charging and starting systems
- Alternators and starter motors
- Wiring faults, shorts and batteries that keep going flat
- Lights, power windows, central locking and accessories
- Sensors, warning lights, fault codes and module programming
- Electrical parts of air conditioning and hybrid systems
Problems that could be either
| Problem | Could be mechanical | Could be electrical |
|---|---|---|
| Car won’t start | Seized engine, fuel delivery | Battery, starter, wiring, immobiliser |
| Check engine light | Misfire, worn parts, leaks | Faulty sensor or wiring |
| Air conditioning blowing warm | Refrigerant leak, compressor | Fuses, relays, pressure switches, fans |
| Overheating | Radiator, water pump, thermostat | Electric fan, temperature sensor |
| Battery keeps going flat | — | Alternator, parasitic drain |
If you’re not sure which it is, start with whoever can test both. Our guide to a car that won’t start but the lights come on walks through the most common case.
Are they different trades?
Yes. In Australia, automotive electrical and light vehicle mechanical are separate trade qualifications. In NSW, a business that repairs cars for payment must hold a motor vehicle repairer licence — you can check any repairer’s licence on Service NSW.
Why BOSS 1 does both
BOSS 1 – Electro Mechanical is a licensed mobile mechanic and auto electrician (MVRL 60872) based in Merrylands. Because we cover both trades, one visit can test the battery, alternator and starter and fix the mechanical side too — no booking a second trade, no tow between workshops. See our services.
