The indicater meter is a DC device, so the rectifier changes AC to DC. A meter could not respond to AC.
The current that is transferred through cables over long distances is AC. The main reason for this is because it is easier to handle. For example, it is easy to convert an AC current to a higher or a lower voltage with transformers. Transformers don't work for DC.
bridge rectifier is the best rectifier.
A three phase alternator will have six diodes in the rectifier bridge, three with their anodes connected to the phases, and cathodes commoned to the positive terminal, and three with the cathodes connected to the phases, and anodes commoned to the negative terminal, which is likely the housing of the alternator. The trio diodes arrangement will match the positive rectifiers, i.e. anodes to the phase connections, cathodes (denoted usually by a stripe around the body on small diodes), connected to the D+ terminal
Working the rectifier
The alternator diode rectifier converts the AC current being produced by the alternator to DC from which most of the electronics installed and battery use.
Are you referring to the Rectifier in the Alternator? Simply, a rectifier turns the AC voltage produced my the alternator to run the electrical components in your vehicle and turns it into DC voltage to recharge your battery.The purpose of rectifier assembly is to turn the AC voltage. This is in a car.
An alternator produces AC current but it is converted to DC by the rectifier inside the alternator.
Stator, armature, rectifier, bearings, brushes,
Inside the voltage regulator on the alternator.
The diodes are part of the rectifier assembly that converts the alternator's AC output to DC. The alternator's charging output flows through six diodes in the rectifier assembly before it goes to the battery and electrical system.
A rectifier can convert AC to pulsating DC.

A diode is used primarily as a Rectifier
Is the alternator a known good one? You could have a bad rectifier in your alternator causing a short to ground when it is installed.
