Still Having Electrical Problems AFTER Replacement of Alternator.That situation suggests that you have one or more of many possible problems which probably existed even before you replaced the alternator. Replacing the alternator did not correct the preexisting defect.It also suggests that there was nothing wrong with the "old" alternator and you wasted a lot of money replacing it.The proper "fix" for this situation is that you need to have a qualified automotive electrical Technician properlytrouble your vehicle's electrical systems, identify the defect(s), and properly repair the defect(s).NOTE my repeated use of the word PROPER. It the job is not done properly then you will continue to have expensive problems and repairs.
