Does alternator on weak battery affect the RPM?
If you have the wrong size battery in a Cadillac with the northstar will it effect the alternator voltage?
Why voltage regulation is required in alternator?
To regulate the voltage flow going to the battery.
Why does my Car stall when you unhook the battery?
It means that you have an alternator fitted. An alternator needs an amount of battery voltage to generate electricity. A generator/dynamo will make voltage without a battery being present.
Would an alternator burn a battery up?
If the voltage regulator (usually located inside the alternator) were to go bad and not limit voltage to the battery quite possilby _yes
How much voltage the alternator of Skoda octavia gives?
the alternator voltage at the battery should be between 12.4voltsv-13.6 volts
What causes alternator not to charge battery?
Defective alternator or internal voltage regulator is bad.
On a F-450 what causes the alternator to not recharge the battery?
either the alternator or the voltage regulator are no good.may also be a bad battery
How does an alternator keep a cars battery charged?
An alternator has diodes which transform ac voltage to dc voltage so that the battery gets negative and positive current on its poles thus making the battery to be charged.
How do you know if the battery is no good on a 2000 ml320?
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.
What does the Low Battery Voltage message indicate on Volvo S80 2001?
It means the battery voltage is low. Can be the battery is defective or the alternator is failing.
How do you measure the voltage on a car alternator?
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
How do you fix an alternator that overcharges your battery?
On most vehicles today the voltage regulator is built into the alternator. If that is the case then just replace the alternator. If the voltage regulator is external on your vehicle then replace the voltage regulator.
