'99 civic auto y7.
Girlfriend's car died on her sitting at an intersection waiting to turn left. She was able to get it restarted and move a couple feet, then it died again. Restarted and died a couple more times before she was able to get through the lights and pull into a parking lot.
Apparently the battery light was on during the dieing and restarting attempts.
I left work to go meet her and get the car back home.
Car starts fine for me a few times, no battery light turn on a bunch of loads and everything seems fine.
Get the car home (maybe 5 min drive) shut it off and put my meter on the battery: 12.99v.
Start the car with no loads and get 14.5v
Then I turned on everything electrical that I could at once (blower, rear defrost, mirror defrost, stereo, all the lights, high beams, four ways, brake lights, heated seat (cigarette lighter)
Checked the meter a few times and it was dropping every time I turned on more loads as expected. Got down to 12.5v.
Then after a couple minutes with everything still running I checked again and it was down to 12.2v
Shut the car off and the voltage went back up to over 13v.
Checked 10-15 mins later and it's down to 12.8v
Battery is a little over a year old.
Do you guys think the alternator is on the way out?
I haven't noticed the lights pulsing, or belt noises.
Any help is much appreciated

Figured it out, the cheesy battery terminal clamp wasn't gripping the negative wire properly any more
