I replaced the alternator with a brand new internally regulated one. Jumped the wires together from the old external regulator and works beautifully. That is until I put lights on and then it squeals like a pig. Shut the lights off and the sound goes away. Belt tension is great. Would I be better off getting an alternator with an external regulator and using the regulator that's in the car already? Would the alternator squeal if it is underpowered? The new one is only 75 amp at idle and goes up to 100 amps max. Any ideas?
