NVWindow, on older cars like mine, purple is usually for primary (12 volts), or sometimes pink. If it goas to your dimmer switch, I would guess it is your unswitched 12 volts but I am not sure. If you say big meaning larger guage than the others this would lead me to think that even more so. Can you get a voltmeter to check that? Or do you have a friend that can help you? That would be best. What is your trouble?

supreme3.4dohc, what kind of question do you have about the alternator?
