What voltage should your alternator produce?
Charging Voltage RangeOn vehicles with a 12 Volt electrical system the alternator [or generator if so equipped] output voltage is considered acceptable if it is in the range of 13.5 volts to 16 volts.Any voltage below 13.5 volts will not adequately recharge the battery, and anything above 16 volts will tend to cause the battery to overheat, and boil-off the water from the battery.
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 is the various parts of an automotive alternator?
Bushes, bushingings a couple of magnets, the windings a voltage regulator so that it doesn't boil the battery, an aluminum case and some terminals. That's about it.
Can a 40 amps jump start be used as battery charger?
Yes, but you cannot leave it for long periods of time or the battery will overheat and boil acid away. Normally a fully dead battery to a full battery should take about 2 hours to charge up at 40 amps.
Why is your 2000 Honda accord v6 charging 18volts?
The most likely cause is the voltage regulator in the alternator. Modern vehicle voltage regulators aren't serviced separately, so you would just replace the alternator. That much voltage can boil the battery. Typical alternator output should be around 14.5 volts.
If the alternator is good and the baterry is good then why the alternator don't charge on your 2000 Toyota corolla?
could be a couple issues.....first could be ...the alternator only charges the battery when needed. This is controlled by a voltage sensor in the alternator..when the sensor detects a voltage lower than like 10.6 volts the sesor makes the alternator charge the battery...if it charged all the time it would boil the battery dry in a very short time....make sense?...ok Check your battery cables and make sure they are in good condition and do not have any soft areas...this could be a break in the cable (under the sheath)...if you find a bad cable...repair or replace it...start at the battery positive and follow it to the starter solenoid...then check the small guage wire at the battery positive terminal and check it back to the alternator....make sure all connections are clean and tight....hope this helps
What causes a Maximo battery to boil?
could be an overcharging alternator//seems to happen more with 'cheapo' batteries like maximo... need to get a proper AVR test on the electrical system from a competent shop.
What is the voltage output from alternator to battery?
Normal voltage will be in the 13.5 to 15 volt range engine running turning about 2,000 rpms. It shouldn't exceed 16 volts or it will boil your battery. If it does not run in this range then you need to replace the voltage regulator. These days that is usually done by replacing the whole alternator as a unit. It is usually the most cost effective method of repair.
Can a car overheat with the thermostat stuck closed?
Yes it most definitely will boil and all if you fit it in the wrong way.
What Causes Battery to Boil?
Heat and/or short in the weiring .
Why did my cars battery boil over?
It could actually be number of things.... as long as you yourself didn't over charge it. More than likely it's something overcharging your battery. The first thing I would do is get your alternator tested. Most commonly that is the problem. I have heard that some chryslers have computer problems overcharging the battery also, not sure what model you have tho.
What cause the battery to boil on Dodge van 250 1988 new alternator as been put in and also the external voltage regulator?
Borrow, rent or buy a volt meter and test the battery voltage with the engine running. Have someone take the rpms up to about 1500 and test the battery voltage. If it's very much above 14 VDC, you have a faulty regulator. Ideal voltage is 13.5 but if it's anywhere near 17 or more it will destroy the battery. On the other hand, if one or more of the cells are shorted out, normal voltage will cause the remaining battery cells to boil.
