Are the brushes contacting the slip rings on the rotor under spring pressure?

There is an order of washers that are required when replacing the brush holders. If they aren't done correctly, then a non-charging situation can result. Look at #5 in the "GEN lamp (alternator lamp) PROBLEMS" section here:

brushes seem o.k.

Which type of brushes? The ones to solder on or the ones that have a mounting ring crimped on?

everything went back together the way it was

Are you sure? Did you take a picture of the wiring before you started your work?

If the charge light is ON when you turn the key but before you start it, then the brushes have to be touching the slip rings. Please clarify that.
