Why does the voltage meter drop and lights get dim when you turn on the defrost or ac on your 1999 Jeep Cherokee?

The simple answer is - your battery is getting old ! Batteries don't last forever - over time they lose their ability to retain a charge. The symptoms you're describing is that the electrical system is asking for more power than the battery is able to provide.

Have lights and radio but want start on a 1997 Chevy silverodo 1500 series?
you may only have enough voltage to run some accessories. i believe a starter needs at least 9 volts to turn an engine over. how much voltage does yours have?? check the voltage as you start it too with a meter. sometimes and rare it is it may have a fault inside the battery that opens when you put too much of a load on it.
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 you measure DC current?
A: By introducing a very small shunt resistance in series with the source and measuring the voltage drop which a meter will translate into current

What would cause the lights to dim and the belt to squeal on a 98 jeep Cherokee and the volt meter to drop?
Your alternator is bad.
Why don't the left side running lights work on my 2000 Cherokee sport?
If the right side lights are working and all left side lights are out, its as simple as this: Electricity is not reaching the bulbs. Use a volt meter (with the lights on) and check a bulb socket. if there's around 12 volts registering on the meter, then you have power to the light socket and the bulb(s) is/are bad. If there is no power to the socket, that sucks because now you have a wiring issue to chase down. This should be a relatively simple repair as long as u have a volt meter.
What are the types of electrodynamometer?
power meter,power factor meter, frequency meter, volt meter ,watt meter ,voltage ampere meter,
What type of voltage must be connected to a d'arsonval meter movement?
dc voltage
How do you test 220 volts using a volt meter?
Make sure that the test meter is on the correct voltage scale. Place one lead on one of the conductors to be tested and the other lead on the other voltage source conductor. The reading you obtain will be the voltage potential between the two conductors.
How does the technique for measuring current with DMM differ from measuring voltage?
current is measured with the meter in series and voltage is measured with the meter in parallel of the load
What is the problem if the receptacle has 120V on a volt meter but when you plug in a light in the socket the volt meter drops to 25V?
--- Answer --- Most likely the plug is connected wrong, instead of the connecting to the power lines it was connected in series with some lights with 3 times the wattage. When using the meter it will read the potential voltage which is the line voltage of 115 volts but when you plug in the a light, now you completed the circuit adding this light to the other light/s. The reason you get 25 volts is because you are reading the voltage drop of the light that you just pluged in. Where 25 volts? Because the other lights are 3 times higher in wattage give or take. from: bmetong
When the voltmeter is connected across the open in the circuit the meter will indicate a voltage equal to the?
The source voltage.
Where are transient voltage most dangerous?
when reading voltage at the meter base where power comes in the house.
How can you test the voltage of your car battery?
voltage meter.set to DC voltsBuy a cheap volt meter.
Why is it called multimeter?
since it stands for voltage ohm meter :) can measure voltage current and resistance
What is avo meter?
avometer comes from " avo " and "meter". 'A' means amperes, to measure electrical currents. 'V' means the voltage, to measure voltage. 'O' means ohms, to measure ohms or resistance. finally the meter or unit of measure. often reffered to as AVO meter multimeter or multitester. AVO meter is a device for measuring voltage, current, both AC and DC and electrical resistance.
