Not a DVKK member.

Assuming your belt os all good.

If the light is fully on when you first turn on the switch.. there is good contact and ground.

If it only does it when you rev the engine, it may be the internal regulator allowing a deficit of voltage...I think,  and could also be the brushrs that you mentioned.
I would replace the Alt and save myself some time and efford but it is your call. $$$ :D

take it off and get it tested, is it edmonds batteries that has the right rig for testing our alternator?
