A squealing alternator during acceleration often indicates a worn-out or loose belt. Over time, belts can wear down or lose tension, causing them to slip and produce noise. Check the belt for signs of wear and ensure it's properly tightened. If the belt appears fine, the noise could also come from a malfunctioning pulley or bearing, which may require professional inspection and replacement.
