On this you have a generator and a voltage regulator, To test the gen start the motor & test the voltage between the two post where the wires connect with a 12 vt meter, you should have 12 or more volts. with the reg I would just replace it. If replacing the reg Be sure to polerize this system. All you have to do is take a jumper wire and touch one end to the field post on the reg and touch the other end to the bat post on the regulator just so it sparks a little bit.
probably worn brushes in the generator, ez to replace about 15.00$
Sounds like the brushes need to be replaced. Find a shop that can check your regulator, and who can rebuild your generator.
your generator isn't charging. try replacing the brushes. if not then try thesamba.com and look for another generator.
What is it you are using to determine its not charging? The charging system includes basically the generator with its belts, battery, the charging "relay" included in the generator and the wiring. If the battery and battery cables are new and it does not charge at all (battery goes dead in an hour's drive or quicker) then visually check if there's the generator belt still connected, then if it is, check visually that the cables behind the generator are all ok. The first fix if these do not produce improvement woiuld be a repair kit (new brushes, new "relay" voltage controller, and a new bearing); these are easy to put in place after the generator is loose and opened by opening the three or four long bolts on the perimeter, but putting the thing back togethr nearly would require a manual for first-timers. Simple anyway, does not require expensive tools, and the kit is cheap (a couple of dollars). Easier and sure fix is a new generator - some tens of dollars, and includes all the small parts. Just take the generator out, disconnect cables, connect cables to the new generator, install and tighten the belt, and see the lights ! remember also to disconnect the battery before starting to fixture with the generator, and to connect it in the end in order to make the car run...

You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
By brushes, do you refer to the windshield wiper motor brushes, or the generator brushes? If generator...just replace the generator, or ramp up to an alternator. It is cheaper and a lot less hassle. If windshield wiper...well...that one is possible, but dreadfully difficult. Best to look for a replacement motor. I don't think they make the replacement brushes any longer.
In many cases, battery charging gauge fluctuations are a symptom of the charging system not keeping up with the additional electrical demand of a blinking light or wipers or other intermittent electrical drains. I would first have the battery checked to see if it is holding charge. If the battery checks out OK, the likellihood is your alternator is failing. More than probably it is your alternator. Ya probably one of the six diodes in the bridge are open, Or the brushes to slip-ring connections are jumping (dress slip-rings and replace brushes. GETERDONE!
The brushes of a generator are essential components that facilitate the transfer of electrical current between the stationary and rotating parts of the machine. They make contact with the rotating commutator or slip rings, allowing for the collection of generated electricity from the rotor. The brushes also help maintain electrical conductivity and are crucial for the generator's overall efficiency and performance. Regular maintenance of the brushes is important to ensure optimal operation and to prevent wear and tear.
an amplidyne is usually an ac motor driving a dc generator with modifications to increase the power gain available. a small electrical signal can control the position of a large motor using this approach. an amplidyne is a special type of motor-generator, which uses regeneration to increase its gain. energy comes from the motor, and the power output is controlled by changing the field current of the generator. in a typical generator, the load brushes are positioned perpendicular to the magnetic field flux. to convert a generator to an amplidyne, we need to connect, what would be the load brushes together and take the output from another set of brushes that are parallel with the field. the perpendicular brushes are now called the quadrature brushes. this simple change can increase the gain by a factor of 10000 or more.
A generator is a back up of power. A generator can only give so much voltage.

That normally happens if your alternator is not charging, or if your Battery cell is faulty. This will result to your car not starting. One always leads to the other. Do one of 3 things, check if your alternator brushes are still in good shape. Check thetension of your v-belt and that the alternator is tightly installed. Have your battery checked out at your nearest battery centre.
