Go to auto zone and have the alt checked out. The voltage reg may be hanging which will cause all kinds of problems.
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!!
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.
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.
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.
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.
It could be the alternator. Unlike the old generators that generated a DC voltage, the alternator generates an AC voltage. Diodes are used to convert this to a DC voltage. If a diode fails, the AC voltage will come through. Many auto parts stores can check the alternator while it is in the car. That is the first thing I would check.
A: A coil does store energy and this energy will be released after the current is removed is evident by a reversal of voltage across it before it collapse finally with less and less voltage <<>> Using a volt meter to ground, you would see the supply potential coil voltage on the coil end, if the return wire from the coil was open.
