Can a fuse cause an alternator not give enough output to charge the battery?

No. More likely bad brushes or a bad internal regulator.

Charge the definition of the charge of battery?
The official charge of a battery is measured by the specific gravity of the electrolyte. For a good battery and alternator, full charge is noted when the alternator output current is just enough to carry the load, plus a bit to maintain the battery, and the battery voltage is normal.
Will an alternator damage the battery if the charge it put out is 14.10?
No, that is normal. An alternator is good working order will output between 13.5 to 15.5 volts.
Fuse alternator 1995 mercury mystique?
I have a 2.0 1995 Mercury mystique the battery charge light was on no output on old alternator. Replaced alternator No output from new alternator "charge light out" (wiggle test wires& re-check wires) at alternator *still no output* is there a fuse that could be the problem or just another bad alternator... I would check the alternator plug before getting another alternator, it may be bad. And is a lot cheaper to replace.
Why is the output voltage of an alternator regulated?
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.
What are the advantages of alternator over generator?
Higher output for a minimum amount of horse power required to turn it. which means greater efficiency. also more compact. A generator will better charge a badly run down battery due to its lower current output. An alternator will try to charge a battery to fast which may damage the alternator and or battery. It outputs from 13.5 to 15.5 volts at idle, unlike a generator that will not operate at full efficiency at idle.
What should the output of an automobile alternator be?
Alternator Output Voltage RangeGenerally, an automotive alternator is considered to be "good" if the output voltage is in the range between 12 1/2 volts and a maximum of 16 volts.Anything below 12 1/2 volts probably will not adequately charge the battery, and voltages above 16 volts can "cook" the water out of the electrolyte, and cause damage to the battery.
How does an alternator cause a negative draw on the battery rather than charging it It's a 90 Buick LeSabre 3.8. It produces an output charge during idle but draws on the battery in high rpm driving?
The alternator will not draw power from the battery but the rest of the vehicle systems will. If your alternator is not functioning properly the battery takes the toll.
Why would your battery light stay on after you have put in a new battery and alternator?
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.
What is a 2007 Trailblazer alternator output voltage?
The alternator output voltage in most modern 12 volt automotive systems ranges from 13.5V to 14.5V, with the nominally accepted value being 13.8V. The actual voltage depends on battery charge state and temperature.
Why are your headlights dim?
Sometimes the bulbs dim with age but usually dim headlights are the result of a poor ground connection, probably at the battery terminal, or a bad battery or poor alternator output. Your local auto parts store professional can check your battery and alternator for you at no charge. Good luck
Your volt meter reads 16 volts at the battery at idle The alternator and voltage regulator have been replaced Do you have a problem?
Alternator Output Voltage RangeGenerally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts.Therefore, although the output is at the maximum, you do not seem to have a problem.Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.
Why would the battery in a VW Jetta not be getting any charge if it has been replaced but you still have the same problem?
You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
