Standard Ignition VR-489 voltage regulator for the 1993-1994 Nissan Sentra 4-cylinder 1.6L or 2.0L controls the alternator's output to hold charging voltage steady. The car takes one regulator, one per alternator.
A battery warning light, dimming headlights or a battery that keeps going flat can mean the regulator is worn, though a tired battery or a slipping drive belt can be behind them too, so track down the cause before you replace it.
This is a direct-fit replacement for the 1993-1994 Nissan Sentra with the L4-1.6L or L4-2.0L engine.

Is the Standard Ignition VR-489 the right voltage regulator for a 1993-1994 Nissan Sentra 4-cylinder 1.6L or 2.0L?
Yes. Standard Ignition VR-489 fits the 1993-1994 Nissan Sentra with the L4-1.6L or L4-2.0L engine.

No. Standard Ignition VR-489 is the regulator alone. The mounting bracket, hardware and instructions are not included.
What connector and terminals does this voltage regulator have?
This regulator has one rectangular female connector and five male terminals, blade and eye ring types. It is a 12-volt unit.
Can a dim headlight or a battery warning light be a sign of a failing voltage regulator?
Yes, those can be signs, since the regulator controls charging voltage. A shop can test the charging system to confirm what is behind them.
How does the epoxy encapsulation help this voltage regulator?
The epoxy around the PC board is meant to protect it from the failures that vibration or corroded electrical connections can cause.
