My alternator makes a wicked squeal on startup and chirps once I start driving. I replaced it with a new alternator and I get the same noise. I did find the plug was bad so I replaced it with a new one as well which eliminated most of the squealing. I'm wondering if the voltage regulator may be fried already by the old plug shorting the terminals out. I have the main lug wired to the battery side of the starter solenoid, the voltage sensor to the back of the alternator (solenoid lug), the stator in the middle obviously plugs into the single terminal on the side, and the exciter wired to the ignition cylinder in the key on accessory position. Is my wiring right at least? I know it's the alternator because I can unplug it and the noise disappears even with the belt on. I do have 14.5 volts on the battery at idle.
