Hey everyone, been having an issue with the car, like always.. Car was fine, then out of no where while driving on the highway, the car stumbles and CEL comes on for a second, then car goes normal again. This happened a few times and I noticed battery voltage real low (have battery voltage set by dsmlink to show on stock boost gauge). I pulled over and the battery voltage went back up, I decided to drive to my destination and I made it after an hour of driving like this. On my way back home, I took it to Advance Auto Parts and battery tested at 13 volts with 838 CCA out of 850 stated recharge needed. My battery is relocated to the trunk by the way. Alternator tested at low voltage of 12 volts on load and without load.
The next day I had to drive to work, so I risked it since battery was still good and the battery light and brake light went on after a minute of driving. So I turned back and figured it was alternator. I then took out the alternator and took it to Advance Auto and it tested good! I then took it for second opinion to Autozone and they tested it 3 times and it was good! I'm stumped, I haven't modified anything in years, just DD.
Couple days before this, I tested with voltmeter the alternator and it was at 14.5 volts with lights on, 13.8 volts at distribution block, and 13.2 at battery. I'm unsure if this is normal as battery is in trunk. Any more help appreciated!
