Put a voltmeter on the battery.If it reads 12 volts or less,the alternator is not charging.It should read 13 or 14 volts.Make surte your belt is not loose or broken also.
You cannot charge a battery without a battery charger or having it charged by the alternator in your vehicle while it is running.
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.
Should really charge it then test it with a proper battery load tester. All you can do on your own is get a multimeter and check the voltage. Without it running and having sat for a 1/2 hour or so the voltage should be approx 12-12.5 volts. Start the engine and if the alternator is good the voltage at the battery terminals should be 13-14 volts. If without the engine running the battery voltage is 12 or less this may indicate that the battery is not holding a charge. Even then the voltage should go to between 13-14 volts when engine is started showing that the alternator is working to charge the battery. If when started the battery voltage stays around 12-12.5 volts or less I would suspect the alternator. Just to double check there is the main power out terminal on the back of the alternator. With the engine running check the voltage. If 13-14 volts is present at the alternator but not the battery the circuit in between the alternator and battery is suspect. If the voltage at the alternator is the same as at the battery (12-12.5 or less) the alternator or voltage regulator may be defective.
Try having battery charged It may have been discharged to the point that it will not accept a charge and willhave to be replaced After having battery charged check the alternator with a voltmeter - should read approx. 12.8 without engine running and 13.8-14.2 with engine running
Yes, running an engine with out oil will damage it.
The year, make, model and engine info would help.
What you need is an alternator wiring pigtail harness from the dealer!
Yes
no,not really
Not having a thermostat fitted will result in the engine running much cooler, usually accompanied by a loss of efficiency and performance as the engine won't be able to reach its optimum running temperature.
Because without it the computer would not work. It is pretty much the same as having an engine in a car.
Symptoms: Besides having a dead battery.......... If you charge or jumpstart your vehice's battery and successfully get it running to only have it mysteriously die and have no lights, radio, etc.; it is probably you alternator. If your vehicle will run constantly on it's own, but will not start after shutting it off, it could be your battery. If your battery will hold a charge on it's own, but goes dead a while after you start and run your vehicle, it is probably your alternator. Or, if you can get it running, it should have an alternator light that will come on when there is a problem. I would almost bet your car has one... my 1970 ford does.
