What else can I help you with?
Why would a 12 volt car battery give off 22 volts?
it won't. The most you will see from a stationary battery with the engine not running is 12.6 volts. If you are seeing 22 volts with the engine running then the voltage regulator is defective and it will ruin the battery. Most modern alternators have the voltage regulator built into the alternator. Replace the alternator.
How much voltage does a battery produce?
Depends on the battery but they are current sources as opposed to voltage sources Standard AA, AAA, C and D batteries all give 1.5 volts each, but rechargeable NiMH batteries are often 1.2 or 1.25 volts.
If its not the alternator that's bad what is it i have changed the alternator but the lights and everything are still blinking?
You need to check and make sure the alternator is charging. You could have gotten a defective one or if you got a used one it may be bad. Get a digital multimeter and with the vehicle off check the voltage at the battery. Should be 12+ volts with a charged battery. Start the vehicle and check the voltage again, should be 13-14 volts or better. If no voltage increase check the big output terminal (thick red wire usually going to it) at the alternator and see it the alternator is putting out voltage. If no voltage other than battery voltage then the alternator is not working. This is assuming that the alternator has an internal voltage regulator (most now do). Without year/make/model/engine size it's very hard to give you decent direction other that generic help :-) **I am assuming you have tested the battery**
How can you test your alternator if your battery is dead?
A lot of auto part stores will test them for free. Give them a call. Your alternator can only be tested when the engine is running, therefore you will have to get a boost or use a battery charger for the battery. If you have a voltmeter, test at the battery terminals with engine still running, if you get 13.5 to 14.7 volts, the alternator is charging. In some cars, the voltage could go over 15 volts if the battery is close to dead (right after being boosted), but the voltage should go back to normal as the battery gets closer to fully charged. Turn off the engine, the voltage will go down to 12.5 volts if the battery is now charged, lower if is not. If there is no change, the alternator is not charging. KGP484
Why does volt meter read less than 75 volts?
It reads what the voltage is so maybe the voltage source is 75 volts. Without stating what the voltage is suppose to be it is hard to give an answer to this question.
What is the voltage to ground of 13800 volts line to line?
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
How many amps will give you a kW?
Amps can not give you a kilowatt with out a voltage being applied to the question. Watts = Amps x Volts. Amps = 1000/ Volts.
How many volts should an alternator give out on a Nissan Micra 2003?
With engine running at idle you should read 13.5 to 15.5 volts at the battery.
How do you tell if the alternator is bad in a 2000 jeep Cherokee sport?
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.
How do I figure watts if I know voltage and ohms?
Volts time amps equals watts so watts divided by volts equal amps.
Why 380 volts line to line if connect line to neutral is 220 volts?
A voltage of 380 volts is a three phase voltage. On a three phase four wire system, each phase leg to neutral (grounded) will give you 220 volts. This voltage is obtained by dividing the phase voltage by 1.73, as the phase legs are generated 120 degrees from each other. Square root of three is 1.73 divided into 380 equals 220 volts.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
