Had a run of bad weather for a couple weeks so I didn't drive my 2001 S for a while and the battery went dead.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Had a run of bad weather for a couple weeks so I didn't drive my 2001 S for a while and the battery went dead. I hooked the tender up to it, let it charge for several days until the tender said it was just maintaining. It started and I drove it that day, periodically shutting it off and starting it with no problem. Now we're experiencing Love Bug season down here so I haven't driven it for a while again but I had the tender on it the whole time. Went to start it and nothing, just clicks. Tried jumping it off my truck's battery, nothing. Now this is the weird part, I just noticed when I step on the brake to start it, the spoiler goes up and down. What does that mean? A short somewhere? Any help would be appreciated.

POST 2Original post

Battery is dead and most likely has a dead cell.

POST 3 / ORIGINAL POSTEROriginal post

That would cause the brake pedal to trigger the spoiler? Just get a new battery and all should be well? Thanks.

POST 4Original post

Was it outside during the bad weather? Either way, check for moisture under the drivers seat. Also check the battery with a volt meter at the battery posts, then check voltage at the post clamps. Corrosion between the clamps and posts can keep a battery from charging. Low voltage or a corroded battery clamp can cause weird electronic issues.

POST 5Original post

Weird voltages will cause the strangest issues. I've seen worst things happen. replace or have the battery tested, before anything bad happens. Do not continue to try to start car with a bad battery I've seem some the most horrible things (some irreversible without large sums of cash) happen to cars because of incorrect voltages on computer controlled cars.

POST 6 / ORIGINAL POSTEROriginal post

Quotes source post: 399880

No, in the garage the whole time. No moisture. No corrosion whatsoever on the clamps, squeaky clean.

POST 7Original post

And as particlewave indicated, it can be as simple as a bad ground or battery terminal. Of course as all forum diagnostics are concern, certain assumptions are assumed.

POST 8Original post

Then the battery should be checked. Possibly a dead cell like hs stated above. If the battery checks out ok, then the real fun begins

POST 9Original post

What is the standing voltage at rest with the battery charger removed? How low did it go when the key is in the crank position?

POST 10 / ORIGINAL POSTEROriginal post

Took the old battery to Wal-Mart, they said it had a bad cell. Got the Maxx-H7 (94R) touted in this thread http://986forum.com/forums/performance-technical-chat/36071-986-battery-group-2.html , dropped it in and it started right up. All seems well so far. Very relieved that's all it appears to have been and really appreciate everyone's help here. Thank you.
