Battery & Electrical System Check

Battery & Electrical System Check

Modern European cars are packed with electronics — and when something goes wrong electrically, it can affect everything from starting to safety systems. Diana Automotive's battery and electrical check gets to the root of the problem quickly, so you're never left stranded.

What We Offer:

  1. Battery Health Test: We test your battery's voltage, cold cranking amps, and overall health to see if it's due for replacement.
  2. Alternator & Charging System Check: We confirm your alternator is charging the battery correctly while the engine runs.
  3. Starter Motor Inspection: We check the starter motor is drawing the correct current and engaging reliably.
  4. Full Diagnostic Scan: We connect professional OBD diagnostic equipment to read any fault codes across all vehicle systems.
  5. Wiring & Fuse Inspection: We visually inspect wiring harnesses, fuse boxes, and connectors for corrosion, damage, or loose connections.

Benefits:

  1. Never Get Stranded: A failing battery rarely gives much warning — catching it early means you replace it on your terms, not on the roadside.
  2. Protects Your Car's Electronics: Voltage irregularities from a weak battery or faulty alternator can damage sensitive ECU and control modules.
  3. Clears Warning Lights: Many dashboard warning lights on European cars are electrically triggered — we find the real cause rather than just clearing the code.
  4. Essential for Tanzania's Climate: Heat is the number one killer of car batteries — regular checks are especially important in Dar es Salaam.

Our Process:

  1. Battery Load Test: We run a full load test on your battery to measure its true condition under demand.
  2. Charging System Test: We check alternator output and confirm the system is charging within the correct voltage range.
  3. Diagnostic Scan: We scan all available modules for fault codes and flag anything that needs attention.
  4. Visual Electrical Inspection: We check fuses, relays, wiring, and connectors for signs of wear or corrosion.
  5. Report & Recommendations: We give you a clear summary of findings and honest advice on what needs action now versus what to monitor.
