2002 chevy 1500 alternator brown wire

my 2002 silverado has a white and brown wire going into the 105 amp
alternator, i have replaced the alternator and battery, the batt light
keeps coming on  and off, the brown wire is intermitent 12volts; i
take it that it turns the alt on when motor is running, can i run an
12v accessory wire to the brown wire on the alt to bypass this short?

thanks

i dont know exactly what the answer to your question is but i think this site might help - http://www.teglerizer.com/alternator/wiring.htm

Is the alternator only charing when the 12 volts os there? From what i can see in wiring diagrams, there should be a grey wire, and brown wire. Grey should be to turn the alternator on, and brown tells the pcm to turn the charge light on, on the cluster
