there are several possible reasons for frequent fuse blowouts: first, internal short circuits in vehicle electrical components can cause excessive localized current, leading to overheating and fuse failure. second, using non-rated power fuses makes them prone to damage. third, prolonged use without replacement allows oxidation buildup. the primary issue is usually short circuits in electrical systems. when a short circuit occurs, abnormal current surges flow through the fuse, causing it to melt due to high temperatures. this mechanism protects both the vehicle's battery and electrical components. another common problem is improper fuse selection. each electrical circuit requires a rated power fuse. using non-rated fuses will cause them to fail and blow out.
