Yah if the battery is a couple or few years old ditch it......no not in a ditch but at your battery store.
10v sucks.
I'll never forget a friend that installed an amp and didn't know it would stay on all the time and kill his battery if he didn't switch it off so check for stuff that might drain your battery you might of added recently.
The no service needed batterys are like when we were little kids and some big guy is picking on us holding us back with a hand on our foreheads. I'd figure 99% of the batterys still need to have the battery acid level checked.
Did I mention ditch the bit.......get a new battery.

try tapping on the starter and seloniod with a hammer or wrench....

My last car (Toyota) had the exact symptoms originally described here. It went on, intermittantly and undiagnosable, for a year. Finally, it happened consistently enough that I could get it looked out. It was a long, aggrevating experience, caught between a dealer and an after-market shop but end result was:

a speck of dirt in the tab where the wiring goes into the starter.

Everytime it jiggled, it would remake the connection thus being intermittent. I didn't even replace anything. The technician just blew on the connection. Problem solved.

Caveat... I'm not so sure about the 996 since I don't own one, but on every other car, truck and motorcycle I've owned fully charged battery voltage was closer to 14V. As others have said 10V is way, way to low.

10V with no load. Your battery is shot. and if its not, you have one heck of a short. Pull the Neg cable off and check your volts... with no load you should be well above 12 as high as 14. 10 V with no load and even if you jump it.. I dont think your going to fire. The battery is eating it self

I was experiencing a similar problem, but it was only occasional. I didn't want to wait till the middle of the winter to be stranded. The local Porsche dealer took a look at it. I asked him to verify that the ignition switch wasn't the problem (knowing that this has been a frequent issue with others' cars. He said that the ignition switch was fine, but the clutch switch was intermittent. I was hearing it click when I stepped down, but apparently that wasn't enough. The switch was still faulty.

I pick the car up tomorrow afternoon. I guess that I'll know pretty quickly if he diagnosed it properly.

Ok I swapped the battery and it worked fine. I guess it had a dead cell in it. Thanks everyone for your help!

Barn996

Yes, another dead battery is toast. Glad it was something simple for you.

ohdavey6286

me too! I thought when it was not clicking over that I might have a dead starter.

I just normally throw the battery in the same ditch I dump my used oil in. That way it's all in one spot.




And please anyone only running on 10v..... I'm kidding.

Over here the authority's stencil paint a fish at road drains to remind people the drains go to the ocean.

I'll never forget when a milk company of Hawaii had pesticide tainted milk so they dumped it down a plant drain that went straight to the Ala Wai Canal running along Waikiki. The river ran white for a day.

[QUOTE=I was able to nurse a weak battery for a year before it needed replacement.[/QUOTE]

How do you nurse a battery? Give it fluids or aspirin?
Is that like doctoring it up?

Barn996

Exactly. Fluids=topped off with distilled water, no aspirin, but trickle charged it often. Finally winter set in and....it was time for a new one.

So there is great irony in the fact that I posted on the first page and now two years later I have the same problem. At first search I didn't find this thread, but now that I have I too will try the zip tie referenced in one of the links.

I'll post my results once I find two minutes and some shade from this hot weather.

Batteries behave differently than they did many years ago. You always knew when one was on its way out, and it took a few weeks. Even when they died, you could jump-start the car. Now they sometimes are perfect one minute and dead the next and a jump won't work...progress.

I replace the batteries in my boat every three years even when they seem strong. I should probably do that with my cars as well
