- 9Why does my car battery warning light flicker on and off?An intermittent battery light that changes with engine revs usually indicates a failing alternator or a loose drive belt failing to supply proper voltage at lower speeds. This prevents the charging system from maintaining a full battery charge while idling or driving under four thousand RPMs.
- 4Should I replace just the alternator pulley or the whole alternator?Replacing just the pulley is cheaper, but on a high-mileage vehicle near 200k miles, a new alternator is often the more reliable choice. Finding the most cost-effective option can be difficult when trying to balance DIY repair costs against long-term reliability.
- 3Why does my car die right after a jump start?When a jump-started car engine dies immediately upon idling or letting off the gas, it fails to stay running on its own power. This leaves drivers unable to drive the vehicle anywhere since the engine bogs down and cuts out the moment assistance is removed.
