Mitsubishi Alternator Rectifier Bridge

46 items

An alternator rectifier bridge uses diodes to convert alternating current into direct current for the vehicle's electrical system. Choose the bridge for the alternator design, comparing assembly layout, connections and mounting. It is a service component within the alternator rather than a complete alternator replacement.

Alternator Rectifier Bridges

An alternator rectifier bridge uses diodes to convert the alternator's alternating current into direct current for the vehicle's electrical system. It is one part of the alternator, rather than a complete replacement alternator.

A-Premium offers rectifier assemblies for selected alternators. Their size, connections and internal diode configuration can differ, so select a bridge for the specific alternator being repaired.

Choosing An Alternator Diode Bridge

Identify the alternator and compare the replacement's mounting shape, outside diameter and electrical connections. The vehicle application helps narrow the choices, but the rectifier must also match the alternator installed in the vehicle.

A charging warning or a weak battery does not identify a failed rectifier by itself. The battery, drive belt, wiring and voltage regulator are also part of the charging-system diagnosis.

Frequently Asked Questions (FAQ)

What is the difference between a rectifier and a voltage regulator?

The rectifier converts alternating current to direct current; the regulator controls alternator voltage for the operating conditions. They perform different jobs even when both are mounted on the alternator.

Can a faulty alternator diode drain the battery when parked?

A faulty diode can contribute to battery discharge while the vehicle is off. Other electrical loads and battery problems can also cause a drain, so the charging system needs a proper diagnosis.

Why does the battery-post size matter?

The post connects the charging output to the vehicle's electrical cable. Its diameter and length must suit the connection and available space; an M6 post and an M8 post are different mounting specifications.

What do the heat sinks on a rectifier do?

A heat sink helps transfer heat away from the electronic components. Some A-Premium bridge listings identify aluminum heat sinks, but the design and supplied parts vary by product.

Can I disconnect the battery while the engine runs to test charging?

Keep the battery connected while the alternator is operating. HELLA warns that disconnecting the battery or connections with the engine running can create voltage spikes and damage components; use the specified diagnostic procedure instead.
