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.

The fusible links on a 1993 Ford Ranger are located throughout the vehicle and primarily in the engine compartment. They prevent circuit overloads and must be replaced each time they are burned through.
yes, but keep in mind it can drain your battery so your truck won't start. Some inverters automatically shut off to prevent killing the battery,
Internal combustion engines need 3 things to start and run: air, fuel, and spark. First look over all of your fuses, to make sure none of them such as the fuel pump fuse, or the fusable link have burned out. Make sure your battery is not faulty, even a brand new battery could potentially be no good. Check the voltage with your volt or multi meter, it should read around 12.5v. Inspect the cables to and from the battery and alternator, but sure they are properly installed. Check your air induction system, make sure the air filter is nice and clean, no blockages. If your vehicle is equipped with a MAF (Mass Air Flow Sensor) make sure it is plugged in correctly. Likewise if your vehicle is equipped with a MAP (manifold absolute pressure sensor) be sure that is plugged in correctly. Visually inspect the entire length of the intake piping, for loose clamps, cracked piping, or gaps. Once you have completed that if your vehicle has a distributor system, remove the distributor cap and replace it if necessary. If you see any visible damage to the spark plug wires, or the age of them is unknown replace them. Next check your spak plugs for the correct gap as recommended by the manufacturer, be sure they are in good shape before reinstalling them. If the vehicle still will not start, try replacing your fuel filter. This is usually inline, though in some cases it is in the fuel tank itself. Once that is completed turn the key to the accessory position, in most vehicles you should hear the fuel pump turn on and prime the lines for starting. If you do, you should be in good shape at this point.
Mine (5.3L) is on the PASSENGER side underneath the engine. It has 2 bolts mounting it to the block and 2 wires on the solenoid (battery and ignition). Once you remove the two long mounting bolts, you can wiggle it towards the front of the vehicle to remove it (it takes some doing). Remember to disconnect your battery first to prevent any shorts. Battery side of engine low on the engine.
no, the light has nothing to do with the alternator working properly, the light is only to warn you that it isn't charging the battery properly.
Bad alternator, voltage regulator, or battery. Also a loose or corroded cable or bad cable.
YesFirst if the starter is bad the car will not start, if it will not start it can not charge the battery.If the starter will not work it can mean there is an electrical problem that will also prevent the alternator from charging the batteryThe starter itself CAN NOT CAUSE CHARGING PROBLEMS!The extra load on the battery can ruin the battery and that can ruin the alternator. But before that NO.
IF the fusible link has "fused" [opened up, melted apart] it will not keep the alternator from working, BUT it will prevent the battery from receiving the charge.
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alt. You may also have a battery drain (something that is staying on and killing the battery)
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
An alternator is regulated to prevent overcharging of the vehicle's battery.
No, a defective battery will prevent the engine from starting but once it is running the battery will not cause hesitation. the the starter relay is disengaged , and the alternator takes over battery charging via voltage regulator . voltage regulator prevents power surges and prevents voltage fluctuation.
TestBefore paying money for a new alternator (which I was about to do today), be sure to have the alternator tested. As many people suggest, Auto Zone, and other parts suppliers, will test it for free. You may have bad connections into your alternator...make sure they are secure and free of corrosion. You might also simply need to tighten the alternator belt. A loose belt will also prevent the alternator from charging the battery. Cable testTry this: With the vehicle running, disconnect the negative cable from the battery. If the vehicle keeps running, the battery could be bad. If the vehicle dies, the alternator is probably bad. Most major auto parts stores can test batteries and alternators. Note - the above answer states that you should disconnect the negative cable from the battery. 'The correct answer is to remove the POSITIVE cable not the NEGATIVE.constantly deadYour battery is there for starting purposes only- once you start the car, the alternator/generator takes over, and runs the cars electrical system (and recharges the battery)- if you start your car and then disconnect the battery, if your alternator is good, the car will keep running. bad alternator and the car will die. note that if your alternator is bad, your car can run off the battery for a while till the battery dies. sure sign of bad alternator = constantly dead battery. Additional Answersstart the car the remove positive battery terminal if car stalls or idle drops really low alternator is badMy battery indicator light came on, but the car would still start and the alternator belt was intact. I tested the alternator with a volt meter and sure enough it was bad.Battery continually going dead. Best thing to do is drive the car to an Auto Parts store and have the alternator load tested.If you do not have a voltage tester bring it to a repair shop and have them test the alternator. Puts out between 13-14 volts. If under 13 it is probably badYou can always start the vehicle and disconnect the battery. If it dies, your alternator is the problem. If not something else might be the problem.start or jump-start the vehicle. Remove jumper cables after it's started. Use a volt meter to find out the voltage at the battery. If it's below 13.5 VDC, the alternator is probably bad. Take it to an auto parts retailer and they'll usually test it for free.
Yes...never try to charge a dead battery with an alternator. It can cause sudden alternator death. There is a paper that comes with many rebuilt alternators that recommends always charging a dead battery before running the vehicle to prevent sudden alternator death.. Good advice.AnswerThe alternator will have to work very hard until the battery is charged fully. If the battery is zero volts and has a low resistance to the charging current from the alternator, the alternator will be under extreme stress, but this could not happen because the electric current used to power the magnetic field inside the alternator runs off of the battery--this is a natural fail-safe against huge damage being done. There is also a charge regulator that normally is in the circuit that prevents the battery from getting too much voltage or current from the alternator. If this circuit is damaged or badly designed, then that portion of the electrical system in the vehicle could be burned out.There are usually about 6 high current low voltage drop diodes inside the alternator that can be damaged if excessive current is drawn from it to try to charge the battery or power the vehicle's electrical accessories. These can fail or be damaged and about to fail in the near future. It is possible in some alternators to repair them by replacing some of these damaged diodes. The repair task becomes useless if the electrical windings of wire inside become shorted or damaged due to burn out temperatures being caused by excessive current flow--then it is time for recycling the unit and getting a new replacement alternator.
No. When a laptop is plugged in, it immediately switches to AC power and begins charging the battery. The battery cannot become "overcharged" because special circuitry in the battery is designed to prevent this.
To limit the rate at which the charge is put into the battery in order to prevent overheating, boil-out of the water in the acid electrolyte, and eventually ruining the battery.
