Just Ensure that you faucet gently and evenly aroung the OUTER RACE ONLY on The brand new bearing when putting it in to the housing.
An additional terminal "turns the alternator on", or offers a sensing voltage to the regulator: it normally will get twelve volts from the "ignition switch on" circuit. The third terminal generally goes on the "alt" or "bat" warning mild.
ROTOR: The rotor assembly includes multiple "pole shoes", copper industry windings, and also the slip rings, all mounted about the central shaft of your alternator. A number of "N" and "S" poles on the rotor pass across the many sets of stator windings (in groups of three) to create 3 phase AC current.
On most other more mature motor vehicles the regulator was mounted about the inner fender or perhaps the firewall.

Most newer motor vehicles Have got a voltage regulator which can be Component of the alternator, but older vehicles possess the regulator being a independent component. Some Chrysler products and solutions applied the car Laptop to function the alternator. Other makers have not long ago resurrected this follow of making the voltage regulator A part of the pc.
