Normally those systems as Abs and Air Bag needs a constant and stable power supply,and your battery maybe is corroded internally nad does not hold the charge. The computers in those systems performs a system check,which measures the battery's capacity to hold and handle the amperes requeriment of these systems,the ABS makes a complete cycle of the electrical motors and they have electromagnetic brakes which draws a lot of power. Install a new battery and your problem will be solved,maybe you need to erase codes for low voltage in the system. Your alternator is likely dead. My 1999 Grand Am is on it's third now (119K miles).

Because when a car is started the starter motor draws power from the battery at the same time as the lights, leaving less power for the lights so they dim.

The magnatron is not recharging the battery or the lights are drawing too much power to allow the battery to recharge. The best thing you can do is when you are done riding, turn the lights off and allow the machine to run for a while to recharge that battery.

The car will not start after driving for a period of time. The lights are very dim while the engine is running and get darker , or the battery light is on in the dashboard.

When you car is turned off your battery doesn't have the alternator pushing that constant stream of voltage to your battery to keep it charged. So your looking at a decrease in voltage by 2 - 3 volts while car is off. No part will fix this just simply start your car before you turn on your head lights.

extra battery creating a start situation indicates loose connection or bad battery. I have also seen starters be damaged in the fields and armatuer that will activate with extra power.

If it runs for a little while then dies it could be your alternator.. If it ticks or just does nothing its either your battery or starter.

User Avatar

Do the headlamps work while cranking the starter? If not focus on your battery and cables. Jump start the car and have the system tested before you throw more dollar bills at this problem; it could be the alternator but have it tested first.

The car battery. Same as the lights, cigarette lighter, windshield wipers, power windows, power seats, and the heater (for a little while), when the engine is off.

Replace the starter solenoid which is attached to the positive battery cable. Also clean both battery cables and inspect the cables while you are cleaning them.

Sounds like the battery has gotten weak. If the battery has been replaced recently maybe the alternator isn't charging it up. Some auto parts houses will load test the battery for you and tell you if it is weak. They can also check to see if it is charging the battery while it is running.

with today cars there are several relays which are used to send electricity to certain parts of your electrical system, such as a fuel pump relay, or a starter relay. one thing i tell people to do is have some one try to start your car with the lights on if the lights go off while trying to start the battery is dead . if the lights stay lit with very little dimness then you have a starter problem. Could be loose or dirty battery terminals, bad cable, starter solenoid. load test battery just because it has 12 volts does not mean there is enough amps to turn over check corroded terminals especially side terminals pull them off and pull bolt out and check both sides for corrosion

If its an old battery the cells could be dried up, meaning there is not enough battery acid in it, or if you leave your lights on, or a bad alternator could be causing the battery to not charge while the car is running.

Turning Parking Lights ON while Charging BatteryNO, it serves no purpose other than to reduce the life of the parking light bulb filaments, and to cause the battery to have to be charged longer.

User Avatar

Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.

By checking battery voltage while the engine is running and the lights are on.

Bad alternator and/or belt. Your battery isn't being re-charged while you run the engine, so the electrical things drain the reserve from the battery.

User Avatar

Maybe you have a problem with your car's battery. If your battery's dead, your interior lights and radio wont turn on. So if you wait for a while and your radio wont turn on, then probably the problem is with the battery. If it is, than you should check the your battery fluid. If its not the battery, maybe there is something wrong with your starter motor.

because the voltage the car battery can supply is not sufficient to start the car engine but the light demand little voltage to be lighted' by GARIBA MOHAMMED-SUNYANI POLYTECHNIC/GHANA

Battery connections. The starter should NOT have been touched during the operation the battery had to have been removed. Make sure all your grounds and connections are corrosion free and properly installed. Lights is not an indication there is good contact from the battery. They need little contact to operate while the starter needs a fair amount of contact. Only other possiblity is the ignition switch, Clutch switch(if manual), or Park switch (if auto) is bad

User Avatar

Probably your battery cable or cables are loose on one end or the other.

User Avatar

Your car lost power while you were driving and it will not start now because the battery is depleted.

User Avatar

If your car does not turn over that usually means that your battery is dead, also accompannied with a lack of interior lights, guages, etc. when the key is in the start position. You should be able to start it with a jump. Also check for corrosion around the battery terminals, could be the cause. If it hasn't started for a while you will need to let it run for a bit to recharge the battery.

User Avatar

If your vechicle does that it means that your battery was dead and after a while of cranking it sometimes it gets charge and starts

User Avatar

Check Battery connections are clean and tight. If they are OK, then the problem lies in the relay mounted in the starter (it is one unit)
