if it is like a ranger there is a plug on the driver's side wheel well that looks connected but squeeze it together it should work
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
Battery may have a dead cell and need replacing.
If the battery was charged when you installed it, you do not have to drive the car at all. If not you should charge the battery and not use the cars alternator to charge it.
The battery has a dead cell or short and needs replacing.
I'd suspect the alternator. The vehicle can run off a minimal battery charge, but if the alternator has failed the battery will eventually discharge. Understand that a battery is simply an electrical energy STORAGE DEVICE. The battery is there so that the engine can be started, but once the engine is running the alternator is supposed to re-charge the battery, replacing the electrical energy that was used to start the engine. BTW, automotive batteries are not designed for "deep cycle discharge", and you should try to avoid that if possible.
alternator probably needs replacing not charging battery or bat is dead and not taking charge
=== === Some types of electrical shorts do cause the battery to discharge. But usually a bad alternator just does not charge the battery. Or does not put a large enough charge back into the battery. This causes the battery to discharge when you start and run the motor. The spark plugs and other things need electricity that would usually come from the alternator is now coming from your battery. If your bad alternator is not recharging the new battery, the battery will soon fail to start or run your vehicle. You need to have your alternator tested. It should be putting out at least 12 volts, usually around 13 to 15 volts.
A battery charges nothing it accepts a charge from the alternator.
Charge the battery.
older cars had a generator ,not an alternator, but you can always use a battery charger to charge a battery
Connect a battery charger to the battery and let it fully charge. Do not charge it with the cars alternator. If it will not accept a charge the battery needs replacing. Connect positive (+) red cable to positive post and black negative (-) cable to negative post. Trickle charge the battery do not fast charge it as the charge won't take. Sure it will start the car a few times but a good charge to a battery is one that is done slowly
No, the alternator is the charging device which runs off a belted pulley attached to the motor. The alternator charges the battery which is the source of the current required to get the engine turning over and in turn starting the engine.
