I need a little help here , just finished rebuilding my generator .Which direction should the generator rotate when bench testing for rotation , looking at the gear end?

CW

You should first lift the third brush and try if the generator rotates with battery power. If it does, try loosen the four small screws in the back end and turn the whole brush plate slightly until the rotor won't rotate.

After you let the third brush back down it should rotate in the proper clockwise rotation as John wrote above. Adjust the third brush until it draws x amperes ( I think the club booklet writes 11 amps, but it may be a bit high?) and put it on the engine for a final test and adjustment.

Correct setting of the charging depends on how much you drive with the lights on, etc - but the generator doesn't like to produce more than about 10 amps at 7 volts continiously, that's 70w. Much more and it risks overheating and won't last long.

When setting up the generator you need to find the null point, where it does not want to rotate CW or CCW. This is done by adjusting the brush plate.

Thanks a lot , at first it was rotating ccw, I then changed the leeds from the field and it was rotating cw. Just need to get it back in the car and set the third brush.

I should have added but "wants" to rotate CW. Unless you have one of those funky field windings the leads should be crossed.
