Chosen Solution
I have a 2008 Saturn Outlook. The alternator was replaced about 8 months ago and a new battery bought today. My problem is when I take off my charging bolts drops under 13v. That’s when my system repays that my charging systems needs to be check. I can put the vehicle in neutral or come to a stop and my bolts goes back to normal. I can get on the interstate and once in the on ramp my volts goes under 13v and as soon I put it in neutral on the highway it goes back to charging over/at 13v. When I put I back in drive it maintains the proper volts. It only goes low when I take off. I’ve changed the belt and the problem is not solve. Help me if you can.
Hi @leevi3rd , There may be a problem with the car’s voltage regulator - example only not maintaining the correct output.
