Auto Electrician Services

A car electrical diagnostic pinpoints faults in your vehicle’s wiring, sensors, battery, alternator, starter motor and onboard computers. At Lube Mobile, our mobile auto‑electricians use professional scan tools to read fault codes, test voltage and charging output, and trace any wiring or component failures.
 

The goal is simple: find the exact cause of the problem quickly, so you avoid guesswork, unnecessary part replacements, and ongoing electrical issues. We come to you, run the full diagnostic on‑site, and explain everything in plain English.

A dying battery and a deeper electrical fault can feel very similar, but there are a few signs that help separate the two:
 

Signs of a failing battery

• Slow engine cranking
• Clicking sound when you turn the key
• Battery warning light on the dash 
• Needing jump‑starts more often  • Battery older than 3–4 years
 

Signs of a broader electrical issue

• Lights flickering or dimming while driving 
• Electrical accessories cutting out 
• Burning smell or hot battery terminals 
• Alternator or charging system warning light 
• Random warning lights appearing
 

If you’re unsure, Lube Mobile can test your battery, alternator and charging system on the spot. We’ll tell you exactly what’s failing — no towing, no hassle.

When your radio, dashboard, or multiple accessories suddenly shut off, it’s usually caused by one of the following:
 

• Blown fuse or relay 
• Loose battery terminals 
• Alternator failure causing low voltage 
• Faulty ignition switch 
• Short circuit in the wiring 
• Bad earth connection
 

In many cases, the car may still start — but the electrical system is unstable and could fail completely. Lube Mobile can come to you, run a full electrical diagnostic, replace blown fuses, repair wiring faults, or test your alternator and battery on the spot.

Flickering lights when braking usually point to a voltage fluctuation somewhere in the electrical system. Common causes include:
 

• • Weak or failing alternator
• • Poor battery condition
• • Loose or corroded earth (ground) connections
• • Faulty wiring to the brake‑light circuit
• • High electrical load causing voltage drop
   

Because your brake lights activate every time you slow down, any weakness in the system becomes obvious. Lube Mobile’s mobile auto‑electricians can test your charging system and wiring at your home or workplace to find the exact cause before it becomes a bigger safety issue.
