I ran a few errands in the 996 over the weekend and on the last stop to the supermarket I came out to a dead battery.
Leading evidence: 'Run few errands in the 996 over the weekend' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check battery voltage not' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
If you have a multimeter check the battery voltage not running when it has been disconnected from a charging source for at least an hour.

Suggestion
The source of the problem has to be determined through testing; surely someone locally that can do that.

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.

I believe I may have an alternator problem on my 996.
I ran a few errands in the 996 over the weekend and on the last stop to the supermarket I came out to a dead battery. The battery is almost new (only six months old) and my trip was fairly long so the alternator should have that thing fully charged.
Got a jump and the dashboard voltage gauge jumped up to 14 volts, but quickly dropped to under 12 on the drive home. I hooked up my battery charger overnight and went out again for a very short trip the next day. When I started the car I had about 14 volts on the meter, but this dropped to under 12 about 3 miles from home.
What does your voltage gauge read on your cars when you turn the key (prior to starting)? How about when you are driving down the road?
TIA
Ray: Nearly certain charging issue. Many auto parts places will test for free. Be suspicious of internal voltage regulator, which can be replaced at a fraction of the cost of the entire alternator -new or reman. Sourcing the part can be difficult, but others on the forum have found them. GL
Went to Autozone and had them check it out. I definately have a problem with the charging system (alt or internal voltage regulator). I was not getting any positive charge at all from the system and battery voltage was falling as the car was running.
How do I find out which?

The source of the problem has to be determined through testing; surely someone locally that can do that. Also lots of info on the web. GL!
If you have a multimeter check the battery voltage not running when it has been disconnected from a charging source for at least an hour. Then start the car and with it running for at least a couple of minutes and ilding check it again. Now with it revved up a bit say 2500+ Rpm check it again.
First check should be lowest and third highest, if everything is working in the charging system, if third is lowest the alternator/reg is bad. If second and third is higher than first, battery is bad.
This is a simple and rudimentry check that can give you ideas what to look at. GL
