2004 Chevrolet Blazer electrical issue while running.
Lately I have been having electrical issues while driving. The issue is that while driving
down the road the volt meter will drop below the 14 volt mark and further when I turn on the
AC. When I apply the breaks and put it into reverse it will drop even further when I go to
back into my driveway, by this time it will have dropped down almost around the 9 volt
mark.
I have replaced my neutral safety/backup light switch, battery, and alternator. The issue
was there before I replaced the items. The neutral safety/backup light switch was replaced
because the locking mechanism to shift would not work sometimes, and my backup lights
would not come on unless I put it in park first. The battery and alternator were replaced
about 6 months ago because they were both bad.
I have worked on many vehicles but with this issue I have no clue where to start. I would
greatly appreciate any recommendations. Thank you in advance.
