Is created from the AC voltage from an alternator?
An alternator is so named because it produces alternating electrical current. This energy can be converted from one voltage to another using a transformer. Thus, the 12-volt AC output from an alternator can be transformed into 120 volt-AC current.
What should the voltage regulator be for an alternator?
The manual says the regulator should keep it to a max of about 14.5V. I put a brand new and fully charged battery in at the same time the alternator was changed, so I don’t think the battery can be blamed.
Why does my alternator not turn on when fully charged?
This is because the voltage output of the alternator must greater than the battery voltage or current will not flow into the battery, which on its own should produce about 12.8 volts when fully charged. If you normally see system voltage that is above 14.5 or below 13.8 when flying, you need to find out why.
Can a car alternator run over 14 volts?
“if you fitted this alternator to a vehicle with a flat or faulty battery it will perform eratically . most alternators are engineered to charge up to 18volts for short periods of time to replenish low battery voltage or cope with high electrical loads” I am not sure I believe this, is it true?
Can a remote sense alternator be too high?
assuming there’s not much voltage drop between there and the battery. Other alternators are “Remote Sense” and use a third wire to measure voltage over closer to battery. the alternator thinks the battery is low so obediently goes to full output trying to charge it back up. Here’s some Delco-Remy info on remote sense alternators.
What should the voltage be on an alternator?
In a nice, 70 F (21 C) day, you can expect a voltage regulator charging your car’s battery at about 14.2 volts. And the higher the temperature, the lower the charging voltage. This test is a simple procedure to check alternator voltage regulator output.
Can a dead voltage regulator be replaced in an alternator?
At least a dead voltage regulator in the alternator. The voltage regulator can be easily replaced without removing the alternator most of the time, and usually is cheap so worth a try. Nevertheless, you should definitely clean those connectors and terminals every now and then. – galingong Feb 15 ’17 at 9:25
Is there overvoltage protection in a B & C alternator?
B&C alternators as a rule do not have built-in overvoltage protection, instead relying on the overvoltage protection built into the B&C voltage regulator. At first this seems like an unnecessary addition of cost and complexity, but the B&C setup has proven to be very robust in the field, making the extra complexity worth the cost.
This is because the voltage output of the alternator must greater than the battery voltage or current will not flow into the battery, which on its own should produce about 12.8 volts when fully charged.
