I am new here, first post and i will create a introduction later. Last week i bought a fairly cheap 996 with aero package, but it has some issues to sort out. needs new brakes, oils pressure sensor, fix some oil leaks and a refreshing of the interior. But my main concern at this moment is the charging issue. when i start it in the morning i have a tps/abs and battery light on. i can see it is not charging as the gauge stays at 12v. when revving above 3000 rpm the gauge stays at 12v but the lights go on and off a few times. Then when i start driving the voltage goes to 14v and all lights go out. It almost looks like the alternator needs to warm up.I am thinking about a bad alternator or maybe a bad ground or positive cable. I am a mechanic so i am not afraid to get my hands dirty and like to work on them, but i sometimes do need a push in the right direction.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Generation: 20261027T000231Z · outcome-qualification-6. Deterministic extraction; no AI model inference. How we use sources
Bad voltage regulator. It fails to excite the coils inside the generator and therefore you need the generator to rev higher than idle in order to get it to charge.
