Does the generator have brushes that you can change. it isn't puting any voltage out of generator. thanks

Check for dead shorts by making sure all electrical components are in the off position. Remove the + battery lead. Slightly touch the lead to the + terminal on the battery in a sweeping pass by motion. If you see an electrical arch it is possible you have a bare wire or a compressed one shorting out your system. Start eliminating each component one at time to see what is causing the short. If you are a novice electrical engineer then you might think about contacting a real professional before you burn up the whole shebang.

SOURCE: which post is which on generator on a 1975 sportster?
the post should be the same as an original. The wires should be green and tan. Green wire goes to the post towards the front wheel and the tan to the post nearest the engine. Don't forget to "polarize" the generator before starting. procedure is in the service manual. Momentarily short between the battery positive post and the field terminal.

Did you charge the new battery? Did you check the new batteries electrolyte? I have seen many a new battery come off the shelf, dead! Get one of those floaty ball things and check the electrolytes in the battery, every cell, if one cell is dead, it is no good. The voltage sounds a little low but it should charge up. I don't know what size your battery is, but my old sportster had a car battery in it. Never had a problem. But never left the house without a screwdriver either.

This is unusual since the generator is usually pretty tough. I've got one question. Are you properly "polarizing" the generator? To "polarize" the generator, you need a piece of wire that will reach from the battery to the generator.
"With the generator on motorcycle and connected to regulator, connect one end of a jumper wire to the generator armature terminal. Momentarily touch the other end of the jumper wire to the positive terminal of the battery. This restores the magnetism, Remove the jumper."
This is directly out of an H-D service manual. The 'polarizing" procedure should be done anytime any part of the charging system is removed from the bike. Since a generator produces a DC current, this insures that the current is of the correct polarity.
Also, make sure that the voltage regulator that is bolted to the frame is well grounded. It depends on this ground to regulate the voltage. We usually put one of the "star" type lock washers between the regulator and the frame on each of the mounting bolts. The teeth on the washer dig into the frame and the body of the regulator providing a good ground. And, make sure that you've got the wires properly connected. The green wire goes to the "Field" terminal and the two tan wires go to the 'Armature" terminal. If you need a complete schematic, contact me directly at [email protected]
Good Luck
