If the car is silent, no starter noises then this may be a dead starter with several starts needed on almost every startup. This can lead to premature starter wear. There's a simple test but relies on a good battery and battery connections. With automatic in Park, parking brake pulled, front jacked up to see starter terminals, short two terminals on the ...

The root problem may well be the alternator since if it were bad or failing the battery would not be charged between starts and eventually you'd get to the point where there is no enough energy left in the battery to start the engine. But the first thing to check is the battery connections. Be sure that the connectors on the battery are tight and free of ...

Your + battery cable has one thick wire and one or more thin wires. Look carefully along the length of the thin wire(s) to find an in-line connector that you may have inadvertently pulled apart. The car will be electrically dead if the connector is disconnected.

The sound you hear could be the starter motor turning, but not engaging with the flywheel. You could try jump leads to another vehicle, or swap the battery with another vehicle’s to see if it makes a difference. Can you record the sound you hear and post it so we can listen? Best do this with the hood/bonnet open and put the recording device close but a ...

Take the battery to a local auto parts or battery shop and ask them to load test it. That will tell you if the battery is good or bad. Load testing is much more reliable than a simple voltmeter test because there are many battery failure modes that allow the battery to read normal voltage but it's still defective. Also while you are in there, inspect the ...

It's important to double check your terminology. I expect that your sub-woofers would have the ability to draw power at ten to twenty amperes, not volts. Your battery and the electrical system can provide only a limited amount of power (unknown to me) over a limited period of time. If you want to upgrade an existing battery, consider first the physical space ...

Glad your issue is resolved. However, I just want to educate you (and anyone else who stumbles on this). so, plenty of time to charge a low battery It's a common misconception that an alternator in a car can charge a low battery, but this is incorrect. The old generators would, but an alternator will not charge a drastically low battery. The generators ...

Is it safe to jump a battery that low: not really. Make that not at all safe A healthy battery is about 12.8V by the time it hits 11V, it is massively discharged already. To get to 3.6v, you battery is so discharged that you have already damaged it. Or much more likely, it has already been damaged, causing this voltage. If you jumpstart it, several things ...
