There are three exciter diodes on all alternators. They are connected to the stator windings. The purpose of the diodes is twofold. While the engine is running, it turns off the alternator indicator light and supplies power to the voltage regulator.

What is the purpose of a diode in a car connected after the battery?
I think the purpose is so that the battery doesn't drain itself trying to turn the alternator as though it was an electric motor. The diode only lets current flow in one direction, from the alternator to the battery.
What purpose does an Alternator Diode serve on a 96 Jeep Cherokee 4.0?
DIODES ONLY SERVE ONE PURPOSE , THEY LET THE ELECTRIC FLOW IN ONE DIRECTION ONLY..........SO IT IS PROBABLY THERE TO KEEP THE ALTERNATOR FROM REVERSING POLARITY.
What does an alternator diode rectifier do?
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.
Can you replace alternator diode?
yes
Can an alternator be directly wired to a battery?
Yes, as long as the diode in the alternator has not been removed. Alternator products AC, the diode switched it to DC which is used to charge batteries.
What is the purpose of a diode in an 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.
What makes alternator fuse in 1982 caprice keep blowing disconnected alternator and fuse stills blow?
Im not sure if your talking Alternator output wire fuseable link or regulator exciter wire, i would assume your talking the exciter wire, it may have a short and is grounding out on the engine or frame somewhere
Can an alternator on a Renault Megane with a shorted diode still charge the battery?
It depends on which diode, but sometimes it can.
What causes alternator failure?
Bearings can fail or a diode can burn out. Age is the enemy of an alternator.
Is a diode part of an alternator or the car?
There is a three phase diode bridge in a vehicles alternator. The voltage is generated as three phase AC. The diode bridge converts the AC voltage to DC voltage. This is the DC voltage that is used to charge the battery of the vehicle and run the vehicles electrical systems and equipment.
What device changes ac to dc in an alternator?
diode
Alternator diode location?
Inside the alternator, some are easily replaced and some are soldered in place.
