I'm currently troubleshooting my car's ongoing electrical issues and during the troubleshooting process so far I have gone through multiple OEM alternators and multiple OEM & non-OEM batteries. One of my theories is that out of the box these OEM alternators have faulty components or are simply under powered and can't handle the load of powering both the car's electronics and charging/topping off the battery (even when the alternator AND battery are new and installed at the same time). I'm experiencing system voltage sag - anywhere from 0.5 to 2.4 volts below normal at times. The OEM alternators are rated at 155 amps max. If I get a non-OEM direct fit high output alternator, 240 or 320 amps max, will it help prevent voltage sag?
