Common Problems & Solutions
This often means the starter motor or battery connection is faulty. A weak battery, corroded terminals, or failing starter can prevent the engine from turning over even though interior lights function.
- 1Check the battery terminals for corrosion and clean them with a wire brush and baking soda solution.
- 2Ensure connections are tight—loose cables can interrupt power flow.
- 3Test the battery voltage with a multimeter; if below 12.4V, it may need charging or replacement.
- Jumping the car without checking the dead battery first
- Ignoring warning signs like dimming headlights
