Thanks Eric, I adjusted it and it is now at 14 volts when I am accelerating, but when I am idle, the voltage drops down to 11.8v and my lights will dim, etc until I accelerate again.
I Installed the 220A alternator in my 95 3kgt and at first the belts were squealing so I tightened the belts and it stopped squealing. Now when I accelerate, the battery level goes over 16v and my speakers cut out. Just wondering if anyone has any idea why it is fluctuating so much. Thanks
