Is the belt tensioner holding the new belt tight? Is the belt threaded correctly?

Check all your connections. They should be clean, dry, & tight. It is also possible that you got a defective replacement alternator. HTH. -Jim

b_real, Assuming you have since fixed the flickering lights problem "about a year ago"....Would you mind sharing what corrected that issue? Thanks in adcance!
