Battery won't hold charge - fine for 4 hours or so then dead

I have the car jumped and ran for 1/2 hour or more, then 4 to 6 hours later dead. Use to last 24+ when problem first began.

Turn key, no start, dash dead, but intermittent symptons


First I would look for voltage drop of both end of battery terminal.not a look or seem tight . you have to do it (voltage drop) and terminal at alternator.
now does alternator charging. take voltage of battery
if the problem occur have voltage of battery taken
like I read your problem it looks like wiring terminal ground and positive
the noise you hear is probably low voltage to a relay and the dropping voltage make the relay switch inside relay cycling noise click or buzz

I drove to work fine got back in 4 hours later car won't start battery dead. then got a jump came home turn car off now car wont start.


If you just hear a click, try this:
This procedure usually works:
·Check the battery cable connections:
Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

My 2004 Honda Pilot ran fine then a hour later won't start. At first thought battery so we charged up usig one of those chargers you plug in. Lights flicker, and clicking sounds but won't turn


Check batry terminals are secure & free from corosion, check security of earth strap to engine & main power wire on starter, if ok have the batry load tested to ensure it can perform under load as the starter needs a lot of current. Have you tried a jump start?

WON'T START CONTINUOUS BUZZING FROM SOLENOID


Sounds like the battery is dead. You can try a jump start and see if the car will start. If it does I wouldn't have any issue with replacing the battery and see what happens. You can also measure battery voltage with a voltmeter. You should see 12 volts with the key off, on, or cranking. If the battery voltage is not 12 volts than it is dead or low on charge. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

There is a strong possibility that you may have what is called a parasitic drain on your battery. Which simply means that there is something running in the background that is pulling a load on your battery. These kinds of drains can extremely hard to find. To help you determine of you have a parasitic drain you will need a multimeter. If you do not have one I would recommend taking your vehicle to a trusted automotive service center. Call then first to determine what they charge per hour for diagnostics. usually will be about 1 to 2 hours diagnostics time.

Check to see if you have spark at the coil. If you have spark at the coil and no spark at the plug, you probably have a bad distributor cap and/or rotor.

If there is no spark at the coil, you need to find out if there is voltage present at the B+ terminal of the coil.
No B+ could be anything from a bad ASD relay to a broken wire or burned fusible link.

If B+ voltage is present at the coil, the "NO-SPARK" condition could be caused by anything from a bad Crankshaft Position Sensor (CKP) to a bad Ignition Control Module (ICM) To a bad Electronic Control Unit ((ECU) - AKA Engine Control Module)

Randomly won't start, happened after jumping dead battery


Probably the battery. Take it the chain auto parts place and they will test it for you.
