First, check the status of the AC compressor. Make sure you can turn it by hand while the clutch is disengaged and the engine is off. You should turn it several turns, just to make sure it's free. If the AC compressor isn't turning freely it's most likely faulty. If it does turn freely, check the belt tensioner to make sure it has enough tension to keep the belts from slipping.
13.6 to 14.5 volts with all accessories turned on, depending on temperature.
Normal charging range is 13.0 to 14.5 volts
13.5-16 volts DC
use a voltmeter A fully charged 12v battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 volts with engine running
Automotive Battery VoltagesAssuming your voltage meter is accurate, the battery is fully charged, when the key is turned on, without the engine running, and no accessories turned on, the meter indicated voltage should be 12 volts. When the engine is running and the alternator is charging the battery, the voltage should indicate anywhere between 13 volts to about 14.6 volts.Answer 2 - A wider Acceptable Range13.5 −16 volts is acceptable with the engine running.
It can put out too many volts and destroy the battery but not drain it. The alternator should put out between 13.5 to 16 volts.
Alternator is sending to much volts to battery. Suppose to turn itself off when battery gets to around 13 volts. May need new alternator.
Check the voltage at the battery with the engine running. It should read from 13.5 volts to 16 volts. If it reads lower than 13.5 volts the alternator is defective.
Connect a voltmeter to the alternator and start the engine. An automotive alternator should read aprox 14.5 Volts when it's running and the battery is fully charged.
I'm not sure I understand your question. An alternator will have to produce 13 volts to charge a battery at 13 volts. Most alternators are able to produce 14+ volts but the range is 13.5 to about 15.5 volts.
From 13.5 to 15.5 Volts.
13.5 to 15.5 volts
Not necessarily. There are a lot of factors that can keep you from reading 14 volts at the battery, such as corrosion in the cable from the alternator to the battery.
13.5 to 16 volts DC.
From 13.5 to 16 volts.
That depends on the application [use] of the alternator. For automotive applications, NO, 15 Volts DC is not too much. Generally, an acceptable voltage output range for automotive applications is 13 Volts minimum to 16 volts maximum.
it depand on the alternator and the RPM. Personnally, I tested a 14v 65amp yesterday and i was able to get 51volts
you need the alternator to charge the battery with no alternator when the battery drops to about 10 volts car will not run at all.
around 14-14.5 volts
Borrow a digital DC voltmeter, attach the meter to the positive and negative battery posts, if the battery is healthy and fully charged it should read 12.68 volts, now start the engine and monitor the voltmeter, if the battery is fully charged and the alternator is healthy the meter should read 14.2 volts (give or take .3). If the voltage fails to reach that goal the alternator is probably faulty.
13.5 to 15.5 volts.
Most likely 12 volts if it is on a car. Some boats use 24 volts, or in the case of my boat 32 volts.
