You have a current draw from a accessory on your car. The hard part is where is it? I usually pull fuses/connectors/circuit breakers and look for a spark when reinstalling them. I do this because a current draw is a circuit and when you break that circuit it will cause a small spark.It sounds like you have a heavy draw so I would still suspect the alternator as it has a hot lead even when the ignition switch is off and so does the headight switch...check em out......
Most newer cars will not run at all without a fully charged battery. The alternator alone is not sufficient to handle the operation of all the electronics, let alone headlamps and such. You also need the battery installed just to start the car!!
As long as the battery is fully charged it will start no matter the condition of the alternator. Eventually the battery will run down if the alternator is not keeping it charged.
This may be a dumb question, but did you remember to plug your new alternator in? I installed a new alternator on my truck but never plugged it in, so it wasn't charging the battery and kept dying.
alternator?
It will start if there is enough charge in the battery to turn the engine over. However if the alternator is weak then the battery will not be charged fully.
The alternator either has to be a factory original or a used off of a parts Rodeo,otherwise the alternator will not run.
If the battery is fully charged and the starter is working properly it will turn over and start. The alternators sole purpose is to supply voltage to the vehicle and battery when the engine is running. When the engine is not running the alternator has nothing to do with starting the engine. If the alternator went bad and the battery was discharged then you will have to charge the battery before it will be able to start the engine. Do not jump start the engine with a dead battery if you can avoid it. This puts a strain on the alternator trying to recharge a dead battery and can damage the alternator, even a new one.
No, your battery supplies power to the starter. However if your alternator is defective then it will not supply power to the battery and the battery will soon be depleted.
did you unhook the battery before replacing the alternator
Yes it can as long as the battery is charged . The purpose of the alternator is to put the power used back into the battery.
the battery job is to start the car so the alternator will kick in after the car is running
