I've read the alternator could need replaced (I can not do that), and/or some other part, maybe called "regulator"?

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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Truth told: I'm NO mechanic at all. I have a couple tools, and zero experience. That said... my BATTERY light came on, on dash. My battery was 4 years and 1 month old, so I figure it was down. I did NOT have it on any Battery Minder yet*. I replaced the battery myself HOPING that would be all it was. Test drive, and about 5-8 minutes in, battery light came on again. It FELT like it was powering down just a little then - OR it was my paranoid imagination. I stuck a meter across the new battery while off: around 12.8v while running: about 13.8v I have a Durametric (that I have no clue how to use) and it BRICKED after I updated the software and required a FIRMWARE update. This fail was unrelated and not attached to car. Also have that ODB2 thing and TORQUE on phone which tells me nothing useful that I could find. I've read the alternator could need replaced (I can not do that), and/or some other part, maybe called "regulator"? I forget. Is there anything else I might be able to look into for this? I'm fine taking it in and getting it fixed, just wondered if I have done all I could. Thanks! *I used this work to install the Battery Minder and the new battery is plugged in

Well... you own a Prosche . I think that might be your problem. You may have been scammed. Stick with the original... Porsche. That will solve a lot of headache. Take it to a shop and have them sort out the Prosche problem, first. Then have them look at the battery challenge. /S Cheers!

POST 3Original post

13.8 means that your regulator and alternator are working. I would check major connection points as you may be getting voltage, but low current. There's a large distribution block on top of the engine that is suspect. If the nut holding the cables is loose, this could be an issue. I would also check the cable nuts at the alternator and fusible link block.
