I connected it, got in the car, and checked the voltage, was at 12V on the car's gauge.
Leading evidence: 'Check voltage, was at 12v' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check first thing in the morning' (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.

I had taken it to the shop and had it tested twice but their tests didn't include a ohmmeter check to make sure there was no load.

Had to open the windows and front and rear lids and check first thing in the morning after all the electronics had shut down and the temp was stable.

When you have the alternator checked they usually check output and maybe check for shorted capacitors but I chased a draw for 6 months and finally found it with an IR thermometer.

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.

Bought a new battery over the weekend, and seem to have solved it.
Hi Pelican -
Long time poster, first time 996. I've had a 944 Turbo for a while
I'm having electrical drain issues. It left me stranded the other night, and has been dead a couple time.
I took it to Autozone to test the battery, and they said it checks out ok. Battery is 3 years 3 months old, 790CCA unit from Walmart.
I was just in the garage. Battery was disconnected and reads 12.59V. I connected it, got in the car, and checked the voltage, was at 12V on the car's gauge. I started the car, let it run for 30s, then killed it. Battery gauge in car then reads 11.8V. I got out, walked around for 2 minutes, got back in, and car didn't have enough juice to crank.
Is it really possible I could have drained the battery in 1 start? That sounds like a massive electrical drain.
Similar story a couple nights ago - I had it on the trickle charger at home, drove it to dinner, parked it for 3 hours, and battery gauge in car read 10.2V when I got in - car wouldn't start.
The other test I had run was to charge battery up with trickle charger, then, disconnect it from car. Battery started at 13V, came down to 12.5V quickly, but then stayed there for 12hours.
Suggestions for how I diagnose this?
When you have the alternator checked they usually check output and maybe check for shorted capacitors but I chased a draw for 6 months and finally found it with an IR thermometer. Had to open the windows and front and rear lids and check first thing in the morning after all the electronics had shut down and the temp was stable. Electric use causes heat and I found the extra heat in the alternator (could be something else in other cases). I had taken it to the shop and had it tested twice but their tests didn't include a ohmmeter check to make sure there was no load. Rebuilt the alternator 1 year ago and have had no problems. Put the battery tender back on the shelf.
Do you have a digital multimeter? If so, with the car turned off, disconnect one post of the battery, turn the MM onto Amps / current mode and place it in series with the disconnected post.
The MM will then tell you how many amps are being drawn. If you see more than 1amp with the car off that's massive IMO.
Now how to isolate that? There's a DIY trick for that too. With the MM in place and still reading amps, remove each fuse one at a time. When the MM reading drops to an acceptable level, you've isolated the circuit that's drawing the excess current. From there you'll have to pin-point the draw, however it gets you in the right direction.
BTW - 12V reading on the battery while in the car is low. Each cell is actually 2.1V. A healthy battery on the shelf should be 12.6V.
Also a MM can determine if the alternator is working. While the car is running the battery should read 13-14V. If it's lower voltage when the car is off it's not charging. If it's above 14 you may have a Voltage regulator issue.
Anyways there are a few DIY steps to help.
Cheers.
