What is the function of the brush holder in the alternator?
The brush holder in an alternator keeps the brushes held to slip rings with spring pressure (or commutators in generators or some motors) which provide electrical contact to electromagnets in the spinning rotor. By varying the electrical current through the brushes to the rotor magnets, you can adjust the power output of the alternator as needed.
115 is the RMS voltage. The actual voltage is a sine wave from -167 to +167 relative to ground. RMS stands for root-mean-square, and it a way of saying that 155 Volts of DC would do the same work on the same sized load.
There can be up to 3 phases, and they are the sine wave, shifted by a part of the curve. In most houses, there are 2 phases, and the voltage to ground for each is 110 to 120 V RMS. The voltage between the 2 is 230-240VRMS.
3 phase gets very complex. Each phase is 115 to ground or neutral. 3 PHASE 115V AC EACH PHASE IS 120 DEGRES PHASE SHIFTED THE EFFECTIVE VALUE IS .639 X 115 THE PEAK VALUE OF PHASE IS 1.41X RMS VALUE.

Where is the alternator located in the 1996 Mitsubishi Galant-S and how to you replace it?
Alternator is below the power steering pump, halfway down the front of the engine, on the driver's side. It is a metal "cage" deal which is mounted to the engine block. To replace, you have to slacken the serpentine belt via the tensioner on the alternator, then remove the mounting bolts. This should be done from below the car, with the car on a jack or stands. Installation is reverse of removal. The driver's front fender liner will get in the way of the long bolt. I simply snipped some of the plastic away around where the bolt exits, as it isn't necessary.
Where is the alternator located on 2000 Plymouth neon?
the alternater is on the back side of the motor on the left hand side if your looking at the motor.
What is the voltage output from alternator to battery?
Normal voltage will be in the 13.5 to 15 volt range engine running turning about 2,000 rpms. It shouldn't exceed 16 volts or it will boil your battery. If it does not run in this range then you need to replace the voltage regulator. These days that is usually done by replacing the whole alternator as a unit. It is usually the most cost effective method of repair.

You have something that is ON and drawing current. Suspect, glove box light, trunk light, hood light, brake light, or a possibly stuck power window switch. this is what we thought when we had the same problem, it turns out that our alternator is ran through our computer, and the computer isn't sinding a signal to the alternator to charge the battery, i had to replace my computer and get another battery, i wouldn't drive very much if you have this problem until you get it fixed, otherwise your going to fry the battery and alternater all over again.
