When I park my car for only 5-6 hours, it will start right up again... but
if I park for 11-12 hours or more, I find the battery has drained and
doesn't have enough charge left to start the car.
It's clear to me that the battery is "losing" its charge while being
parked for longer periods -- however, I can't locate the cause. (I have
checked dome lights, all interior lights, radio, air conditioner switches,
fan switches, door switches, in fact ALL switches in the car, and NOTHING
has been left on.)
To verify that "something" is causing the battery's charge to drain away,
I disconnected one cable (the positive one) from its post and late at
night I touched it to the post. Sure enough, a small spark appeared,
indicating that "something" was draining energy from the battery.
Can anyone offer a suggestion? (Could it maybe be a problem in some
component, like a Starter Solenoid or a Voltage Regulator, or something
I know that if I have tests run on this, I could end up having to pay
plenty and STILL they might not find the answer, so I am hoping to find a
solution here -- and I thank you all in advance for your suggestions.
