You must have only the accessory wire hooked up and not the continueous power lead. Both are needed for the radio to keep memory. If just the continueous power lead in hooked up the radio will always have to be manually shut off. The accessory only has current through it if the ignition is activated.
alternator is probably not charging. you need to fix this NOW. new alternator is likely the only repair.
The Battery? No, not typically the battery. That means that the alternator is not charging the battery and IF the engine is running, it's getting all of it's electrical energy from the battery. It means that once the battery charge is depleted, the engine won't run again until you recharge the battery.
either the alternator or the voltage regulator are no good.may also be a bad battery
Your battery is weak, or your your alternator is not charging battery.
Failed battery, or alternator is overcharging.
poss alternator fault
Can be loose or corroded battery connections, loose drive belt, or the alternator is failing.
Alternator is defective and needs replacing.
It's not charging the battery. Check the alternator.
i think you are having problem with your alternator its not charging your battery

Have you cheked your alternator? The battery only starts the car and runs electrical components such as your radio and A/C and lights. The alternator is the generator that keeps the engine running once it has been started. Mine was the fuel pump went out
The positive cable between the alternator and the battery has an open circuit or break. There also is a set of wires that plug into the alternator that turns it on when the car is running. Wiring problems here can cause a alternator not to charge on the vehicle but works fine on a test stand. Some cars the alternator light in the dash causes the alternator to kick in when the engine is started. A burned out light in the dash causes the alternator not to charge.
The most common reason for a vehicle not to turn over is a bad alternator. If the alternator is not charging the battery the engine will not start, regardless of the battery age.
A few causes that will make the Battery Light come on are: 1. Faulty Battery 2. Loose Battery Connection 3. Battery is not Charging, ie. Faulty Alternator
Defective alternator or voltage regulator. Also possibly the battery is defective with a dead cell.
weak battery or bad alternator.
A failing alternator.
Yes, alternators are designed to maintain the battery, or recharge a battery that has been slightly discharged from starting the car. When the alternator is used to recharge a dead battery, it causes the alternator work harder and longer than it is designed for, causing it to overheat, thus causing damage to the alternator. A battery charger should be used instead. They are designed for charging dead batteries. After the battery is charged, let the alternator maintain the charge.
I needed a battery when I was having the same problem.
it means your battery isn't charging from the alternator, could be a fault either with the alternator or your aux drive belt maybe snapped is the most likely causes
The main cause of battery drains is a bad electrical system. The electrical system is normally powered by the alternator and once the alternator goes bad the battery has a hard time holding a charge,
The battery light usually comes on if there is a charging system problem Either battery or alternator are the usual causes.
the common cause why the light is on is that your alternator is not working well,try to have your alternator checked .may be the carbon brush is already worn out.
chances are it's the voltage regulatorit could also be a wire no connected on the alternator
