Generator creates power at whatever rate it is spun, alternators use a regulator to maintain the same amount of power at all times

Is there an alternator fuse on a 94 Cadillac deville


Hello Jamie Pickett,

External to the ALTERNATOR there is indeed a

Diesel generator


What is overheating the engine or the alternator? If it is the alternator check the electrical loads and types, take it to a shop to have it put on an electrical load bank test. if it is the engine, check for air flow and any obstructions. Make sure there is no mechainical binding, remove spark plugs and check compression, make sure engine rotates freely

Not trying to be stupid I know nothing about electrical what are the brush terminals


On motors/generators (starter, alternator, etc,) the brushes make the connection to the rotating armature. You can read up a little on motors and generators. Bottom line is, the brush terminals provide the access point for the outside world - to electrical leads. If you think of an electric drill for something simple...power is applied to the brush terminals, the brushes connect that power to the multiple rotor points as it spins. Slightly different system with DC power but the brushes serve same basic function - providing an electrical contact to something rotating. You may be dealing with a starter or alternator where faulty (worn) brushes or faulty brush terminal wiring is stopping power from getting to the starter, or from the alternator. Does that help at all?

Since the older cars had generators removing the belt had no affect with the motor running until the Battery went dead,also the car would run without a battery because of the permenant magnets in the...


Hi, I am old enough to have worked on both systems. Now, when you remove a belt from the newer or older systems, the engine will run as long as there is enough voltage in the battery. No difference here. The generator dies not have a permanent magnet but residual magnetism in the rotating armature. It would build up voltage and would have to have the regulator control the output. The residual magnetism is a small amount and is similar to the residual magnetism that is currently used in all portable generators or to be correct portable alternators used for your 120 / 240 volt electricity. The car alternator does use a rotating field that relies on an electrical current supplied by the battery through a regulator. The vehicle will still run if the alternator is disconnected, until the battery runs low or an electrical load of sufficient current draw will cause the ignition system to drop out, thus the engine stalls. Remember the same was true of the generator systems as well. I have driven automobiles where the alternator failed and the engine shut down a few hours later. There is no difference with removing the belt or having the alternator or generator fail with the belt on, there is no output to charge the battery and keep the voltage up to run the vehicle. A generator is a device which makes electricity in a DC format. An alternator is a device which makes electricity in an AC format which can be used as AC or converted to DC. Either can have permanent magnets in the rotor. But we use regulators in most cases because with plain magnets, we cannot accurately control the output.

Warning alarm alternator battery malfuntion


The ALTERNATOR generates electrical power, to recharge your BATTERY.

If the belt from the engine is loose/broken/missing, then the ALTERNATOR will not be spinning, and will NOT be generating any energy.

Check the belt; if necessary, replace the alternator.

Alternator replace



Removal & Installation


NOTE There is a trend among manufacturers today to refer to the source of belt-driven electrical power as a -generator-; however, by virtue of the method in which the -generator- produces electrical current the device is actually an -alternator-. The two terms may be used interchangeably.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2. Drain the cooling system.
  3. Remove or disconnect the following:

    Negative battery cable Accessory drive belt Alternator upper mounting bolt Engine splash shield Radiator support access panel Rear alternator bracket from the engine Alternator mounting bolts Duct on the back of the alternator Electrical connectors Front alternator-to-A/C bracket Alternator

To install:
  1. Install or connect the following:

    Alternator Front alternator-to-A/C bracket. Torque the bolt to 37 ft. lbs. (50 Nm). Electrical connectors. Torque the battery connection nut to 115 inch lbs. (13 Nm). Duct on the back of the alternator Alternator mounting bolts. Torque the bolts to 37 ft. lbs. (50 Nm). Upper front bolt. Torque the bolt to 35 ft. lbs. (47 Nm). Rear bracket to the engine. Torque the bolt to 37 ft. lbs. (50 Nm). Radiator support access panel Engine splash shield Accessory drive belt Negative battery cable
  2. Refill the cooling system. 4 DeVille

Can anyone tell me an accurate price to replace a bad generator with an alternator on a 1962 Cadillac Sedan Deville. My local mechanic wants to charge me $1200 and that seems a little expensive.


HARD TO PRICE YOU HAVE TO BUY ALTERNATOR THEN YOU HAVE TO BUY DIFFERENT ALTERNATOR BRACKET SET UP AND YOU HAVE TO REDO SOME OF THE ELECTRICAL WIRING.PRICE WOULD BE $1000.00 RANGE PLUS LABOR TIME.

Honda S2000 engine installed in kit car. How do I wire alternator


Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.
