Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

Turn the key on my 987.2 Cayman (160k miles) and engine won’t start but get a click click click click sound. What could that be?

POST 2Original post

Please forgive me if I'm stating what may seem obvious, but I've been there and asked this forum the same question. In my case, the answer was a dead battery. Eliminate that as a possible cause would be my first suggestion.

POST 3Original post

+1. How old is the battery? Alternatively, how long had the car been sitting? Do you use a battery maintainer?

POST 4Original post

Battery is about 4-6 years old. It is an aftermarket, not sure brand. Replaced the OEM battery that came with the car. Car had been sitting for less than a day. I do not use a battery maintainer. My son, who is the primary driver now, said it had done this before recently, but he was able to start it. Should I try to jump it, and if that works, I’ll know it’s the battery?

POST 5Original post

If you don't have one, get a multitester. Easy way to check batteries (an lots of other electrical devices) and less risk than jumping. Four to six years is getting towards the end of a battery's life.

POST 6Original post

Keep us posted on what battery you buy. Also, has anyone installed the lightweight Braille battery in their daily driver?

POST 7Original post

Luckily YoungTurk has a 987-2 which doesn't require any magic mojo from a dealer to reset/recalibrate. There's many threads discussing common sized replacements. Last time ( 2 yrs ago) I went with this AutoCraft Platinum AGM Battery, Group Size H8, 900A CCA . The extra power also solved a problem I had with OEM. My Pioneer NAV would reboot (due to voltage drop) if I restarted the engine while it was playing. AFA Braille in a daily driver - not much call for that. You'll never notice the weight difference except in competition. There's a couple threads discussing that too.

POST 8Original post

Many thanks to all who responded, especially RSchwerer. Yes, it was the battery. Replaced at Advanced Auto Parts. All is good. P.S. I told my son to take better care of his (my?) car.

POST 9Original post

Singletrack - you were right on the money, thanks.
