Can a dead battery cause a car to not start?
While it isn’t a good idea to just assume the battery is the problem and put a new one in without doing any diagnostic work, a dead battery — or especially a battery that won’t accept a charge — is definitely capable of causing a no-start condition where the lights and radio continue to work to some degree.
How can you tell if your car battery is dead?
Signs the Battery is Dead: When you attempt to start the car, there is a low whining sound. If jump starting gets your engine started and running, but the car will not start again once you turn it off, the battery is probably the problem.
What does it mean when your car won’t start?
Though it might be something else, it’s always good to check the battery first. If the starter motor doesn’t crank and the lights are dim or don’t come on at all, the battery is dead or close to it. The cause can be as simple as leaving an interior light on overnight.
How can I tell if my car starter has failed?
Signs the Starter has Failed: A broken starter will make a clicking sound when you turn the key. The car won’t start, but the dash lights are on. Jump starting your car or truck does not turn over the engine at all.

What happens when a car battery won’t start?
Most commonly, when a car doesn’t start, a bad battery is the prime suspect. The battery plays a vital role in starting the engine. It powers the vehicle’s accessories, but more importantly, it powers the starter or cranking motor. The starter is what turns your engine over, and it draws a lot of power from the battery to do that.
Why is the battery indicator green but not starting?
My 75 1.8 (petrol) wouldn’t start (and no power to any of electrics) so I took out the battery and charged it. Battery charge indicator on the top of the battery shows green which should indicate full charge, but still there is no power to the electrics (i just get a very faint ‘battery’ light on the dashboard).

Why does my car not start when I Turn on the lights?
If it accepts a charge or a jump from another battery and the vehicle starts, then the problem is solved. If it doesn’t start, it may be a blown fuse, a broken ignition switch, or a bad starter. If the battery is in good shape, check for a blown fuse or fusible link.
Can a car battery stop working when the lights are on?
In fact, you can also run into a situation where the lights will work, but the radio will stop working due to the dead battery, and other even stranger combinations. So while your problem isn’t necessarily the battery, it definitely could be.
Can a car battery run on a low charge?
Batteries can sometimes run electronic devices on a low charge. Headlights, radios, and other car electronics draw very little amperage — usually no more than 20 to 30 amps. Engine starters, on the other hand, pull up to 300 amps all at once, which is too much power for a battery with a low charge.
Can a car not start but the battery is good?
If you see the lights working and the radio functioning and thought that battery is good, this is not the right conclusion.
Why is the battery light not working on my car?
The belt drives the alternator, which recharges the battery. If it’s loose or worn, the alternator may not be able to recharge the battery so it can start the engine next time around. (This could also cause your battery light to come on.)
Why does my car make no sound when I start it?
Most likely a dead battery. Start by getting a jump start. Do the lights on the dashboard turn on? If there is no sound when you turn the key, but the lights and accessories work, it could be the stater relay or starter solenoid. However if there is no sound at all, not even a click, it’s probably your battery.
Why does my car not start after I drain the battery?
A broken timing belt, timing chain or timing gear means you can crank the engine until you drain the battery, and it still won’t start. Likewise, a bad crankshaft position sensor won’t send the right signals to the engine computer to allow the engine to start. 8. Smart Key Issue
