WAI Alternator Rectifier Bridge

Alternator issues don’t always mean you need a full replacement. The WAI Alternator Rectifier Bridge lets you replace just the part that converts AC to DC—restoring output without breaking the bank. It’s made to work with specific WAI alternators, especially in automotive and light truck applications. The diode set inside helps reduce current ripple and stabilize voltage, protecting downstream electronics. Often installed during alternator rebuilds, the WAI DR5045 is favored by techs who rebuild instead of swap.
