Because the meter is connected backwards
the voltage regulator
To zero a VOM on DC voltage, leave it unconnected - in DC voltage mode - and then adjust the meter zero screw until it reads zero.
either out of trans. oil , or tranmission is shot
A reading of 145 volts is high. The first thing that I would check is the accuracy of your meter. Check the voltage reading at different locations for example, friends homes, to see if the reading is still high there. If it is check your meter reading against another meter. If you are sure that your meter and reading is correct then call the utility company and get them to check the voltage for you.
A voltmeter uses the principle of Ohm's law, which states simply that the amount of current that flows in a circuit is equal to the voltage applied divided by the resistance of the circuit. Therefore, if one were to connect a known resistance in series with a meter across a voltage source, then the meter deflection would be proportional to the current flow and hence the voltage. The meter is calibrated in volts so that the test voltage can be read directly. The meter used in a voltmeter is very sensitive, typically 50 micro-amperes so that it does not affect the reading by its load on the circuit. pizza is good when volts don't go thru!!
If the circuit is carrying current then that means that the load (resistance) is in the circuit. if an ohm meter is connected in the live circuit then there would be some voltage drop at the ohm meter but as the meter has very less resistance, this would damage the instrument.
you can't repair one you would have to buy a new one and put it on
With a voltage detector or a multi meter. Don't touch the wires to your tongue. That would be bad!
To calculate voltage drop to size the wire, a voltage must be stated.
One of the conditions that would cause this is that there is no supply voltage to the top of the meter. Another problem could be, the neutral tickler wire has become disconnected.
A watt meter that has current through its current coil and voltage across its voltage coil will indicate zero if the power factor between the volts and amps is zero. This condition would be one in which the current will either lead or lag the voltage by 90 degrees and the circuit will have amps, volts, VARS, and VA, but will not have Watts.
You can use either a volt meter and go from the line in question to ground and see if you have voltage. You can also get a non contact voltage tester which is what I would use and place it on the wire in question and it will beep if voltage is present.
To measure voltage be in parallel with the battery. Series would measure current. Parallel measures potential.
An ammeter measures current by either being inserted in series with the load being measured or using a clamp-on device that induces a proportional current that the meter measures. Nothing should happen if you connect an ammeter across a voltage source unless it was very high voltage compared to the rating of the meter.
the voltage "persay" comes from the ecu(computer) i would not use a test light to see if voltage is present thay can be intrusive and short the ecu u will need a dvom meter and service manual to test that circut
If are driving when this happens, it is usually due to a broken fan belt...this belt turns both your water pump & alternator...
A 1993 Ford Aerostar would have come from the factory with ( 5W-30 )
That would be 21 gallons.
A DC motor generates power when it is rotating even when no supply is connected.
There are a few ways one can measure battery voltage. One would be to take it to an auto store like Auto Zone or Advance Auto Parts where they usually have battery voltage meters. If one would like to do it on their own, they would need to purchase a volt meter to test the battery life and to see if any cells are dead.
When connecting a volt meter to a light bulb to measure the voltage of the light bulb, run a third wire from where the wire enters the bulb to one terminal of the voltmeter and a fourth wire from the other side of the bulb to the other terminal of the voltmeter.
No, on dc the power is measured by the produce of the voltage and current so there is no need for a wattmeter, which would not work on dc anyway.
The voltage drop across a relay coil will be the same as the coil supply voltage. If you are trying to see if the coil is good or not, remove one of the voltage supply leads and check for continuity by using an ohm meter across the coil leads. A reading will tell you that the coil is intact and not open.
