Do you know where I can get a pair of gen brushes or are they used on some M/C?
Thanks in advance

Re: generator brushes
You will find most motorcycles don't use brushes in the alternator.
Most are in oil bath except the older ones and they still use a
magnetized rotor & stator.
Look in the Photos sectin in an album call miscelaneous, There is one
that fits a Milwaukee Drill that is exact fit.

Re: generator brushes
You might want to take a look at your alternator. You can connect an ohmmeter to the wires coming
off the alternator, turn the engine over manually, and watch the resistance readings. The power to the engine should be off. You can also remove the brush plate and inspect the brushes and look at the contacts on the alternator flywheel (is it called the commutator?). It should be a clean, shiny, copper appearance and free of oil/dirt.
You may have a problem as simple as a loose connection. When you say the alternator is not putting out a voltage, where are you making your measurement?
good luck,

Re: generator brushes
When you turn the eng over manually what kind of ohm resistance should you see if the alt is OK.

Re: generator brushes
Dale, the only thing I know about electricity is AC & DC and both of them will shock you. But a friend of mine that is a pretty good mechanic when he wants to put a gauge on the wire coming from the commutator
and said it was putting out 4 volts. Getting just enough juice thru to put the light out. Is there one set of brushes or two? Thanks.

Re: generator brushes
When you measure the rotor resistance it should be in the range of 4 to 5 ohms. When you turn the engine over by hand, you want to see the reading stay constant and not jump around by a large amount which would indicate the contact surface needs cleaning.
The manual is indicating the stator coil resistance (the 4 wires coming from the alternator casing) should be about 0.115 ohms between any two wires and there should be no low resistance reading between any one of these fours wires and the casing (i.e. the engine block).
If you are using an inexpensive meter, it may be difficult to make the low resistance readings accurately. Look for a low resistance reading on any 2 wires and look for comparable reading across all combinations of the 2 wires. Check between each of the 4 wires and the engine block to verify a low resistance (i.e. coil has a short) does not exist.

Re: generator brushes
When you remove the plate, you will see 2 brushes. Where did your friend meaure the 4 volts? The place to measure the voltage is at the 4 wires coming out of the alternator casing. Measure between each of the white wires and the wire which is white with the black stripe (this is the common wire on the stator windings). These windings feed into the rectifier which changes it from AC to DC.

Re: generator brushes
Correction....when you measure the stator windings, you want to measure between the each of the 3 windings (the white wires) and the common wire (the white wire with black stripe). The resistance of each of these winding should be about 0.115 ohms. If you measure between any 2 white wires, the reading should be about twice the expected reading (2 x 0.115 is 0.23 ohms).
If you are having problems making low resistance readings, see if you can spot a difference between making the readings between the white and white/black wires and between any 2 white wires. You may be able to detect a difference because the resistance reading is twice as much.
