The voltage regulator for a 1995 Saturn SL2 is in the alternator. Check your charging voltage after the engine is started and has run a few minutes. Should be better than 14 to 15 volts at the battery terminals. Make sure the battery terminals are clean and tight. Had a neighbor replace alternator, battery and starter and all he needed was a good connection to the battery, which I supplied. To load test the alternator, turn on the headlights on high beam, heater fan to top speed and the rear window defoger. Battery voltage should not drop more than 0.25 volts with the engine turning a little faster than idle. Hope this helps.

It is probably a bad voltage regulator. Sometimes they are located in the alternator and can go bad in a new one. On Ford vehicle the voltage regulator is separate from the alternator.

It's an electronic unit in he alternator, it can be removed and replaced, you can find it at the back of the alternator.

The voltage regulator has the job of making the voltage 'constant'. In most modern vehicles the regulator is located in the alternator, in older models the regulator is located separate. If your voltage is jumping around a lot then you either have a problem with the battery (batteries stabilize the voltage also)or the charging system (and probably the voltage regulator)

The voltage regulator is in the alternator on that model vehicle

the alternator has an internal voltage regulatornot all aternators have it internal should be a small sliver box located near the battery.

Voltage regulator is located inside of the alternator.

The voltage regulator is an integral part of the alternator. The alternator is a nonserviceable item.

The voltage regulator for a 1991 Honda accord is mounted on the rear of the alternator. It is bolted on and can be replaced as a separate unit.

The voltage regulator is located, or integrated inside the alternator,and must be replaced as a unit, unless you can find an electrical auto shop that can rebuild it for you.

The voltage regulator is on the alternator, you'll have to take the alternator off to get at it.

No there is not. The only located on the alternator is the voltage regulator.

it's inside the alternator, and is probabaly causeing overcharging of the battery (you might see white foam(battery acid)on the ground under the car) you can't buy and individual voltage regulator though, you have to buy a new alternator

The PCM is also the regulator, it is next to the battery.The PCM is also the regulator, it is next to the battery.

The voltage regulator is locate in one of two places. ***The voltage regulator is located in the alternator if you have an IAR type alternator*** ***The external voltage regulator (for the EVR-type alternators) is located on the driver's side wall, right next to the battery. It's much easier to see and/or remove if you remove the battery first. It has "Motorcraft" in raised lettering across the front*** I just had to remove mine.

The voltage regulator on your 1997 Cadillac Deville, is located on the top of the alternator. Some aftermarket alternators have the voltage regulator, on the back of the alternator.
