If the headlights are dim or do not come on at all, you need to check battery voltage and charging output.ДЇor this, you will need a voltmeter. If the headlights come on with normal brightness, the no-crank problem is probably not the battery, but a bad starter relay or solenoid, a poor wiring connection between the relay/solenoid and starter, or a bad starter. One way to do this is to turn on the headlights. The first things you want to check are the battery and the output of the charging system (alternator). CHECK BATTERY VOLTAGE AND STATE OF CHARGE Your battery is old and will not hold a charge anymore.There is a key off parasitic electrical drain on the battery because a relay is sticking, a module is not shutting down (going into 'sleep mode'), or there is a shorted diode in the alternator.The battery is not being recharged while the vehicle is being driven (you have a charging problem).You accidentally left the lights on or some other accessory that pulls power from the battery even when the ignition key is off.What is wrong? WHY A CAR BATTERY RUNS DOWNДЄ car battery can run down for any of several reasons: The battery has run down and the engine won't crank. The next morning you go to start your car again, and the same thing happens. Now what? You get somebody to give you a jump start, or you connect the battery to a charger and charge it up until it has enough juice to start your engine. You go to start your car and discover the engine won't crank because the battery is dead.
