How Do I Know If My Voltage Regulator Is Bad? Full Answer. To test a voltage regulator, purchase a voltage meter. Connect the positive and negative ends of the meter to the positive and negative terminals on the battery. Turn the car on and push down on the accelerator to get a reading. A voltage regulator is a mechanical part that regulates the voltage of electrical equipment in a car.

VTX1800 Fuel Pressure Regulator Tests to check if you have a bad fuel pressure regulator: 1  Remove FPR vacuum hose, if liquid fuel drips out the FPR is bad. 2  Remove FPR vacuum hose. 3  Hold your finger over the nipple where the vacuum line was and turn the key on (with the kill switch in the on position) so you can hear the fuel pump prime.he VTX fuel pump pushes fuel through the high pressure line and into the fuel rail at a little more than 50 PSI. Depending on the engine’s fuel needs this pressure will fluctuate. It is the FPR’s primary job to stabilize the fuel pressure and prevent these fluctuations.

What do automotive voltage gauges measure? Voltage output of the alternator or the battery's voltage? Answers. Best Answer: Voltage gauges (or a Voltmeter) measure system Voltage. Basically, all 12 volt circuits are virtually the same Voltage at any given time. This does not apply to computer and dashboard reference signals, which are further regulated. Ammeters measure battery charge or discharge in Amps.nswers. Best Answer: Voltage gauges (or a Voltmeter) measure system Voltage.

Thread: Regulate Car voltage? What you are describing is indeed a voltage regulator, not current control. This will step down a variable input voltage to a fixed output voltage. For the above IC to work it will require at least 12.5V in, which you should have at pretty much all times, even when not running, with a healthy battery.

Anyone know where a voltage regulator is located? Either way, the regulator looks like it's inside the alternator, so it was also tested: If the alternator/regulator is 'good', then it's either the battery, cable connections, cable, or a bad ground connection. With a 27 year old car it could be any of those. Bing 2013-11-11 20:12:40 UTC #9.

Car Battery Tester - How to Test a Car Battery In the test apply a load equal to one half of the cold cranking amperes (CCA) rating of the battery for 15 seconds. During the load test, the voltage reading from car battery terminals should not go lower than 9.6V for ambient temperature 70F (21C). At 30F (-1C) the voltage can go no lower than 9.1V.

- Voltage Test. 1  1. Know what voltage your battery is. Most commonly, you will have a 12-volt battery, but sometimes you can have a 6-volt battery. 2  2. Turn on your voltmeter and select DC voltage. Open the hood of the RV. 3  3. Touch the voltmeter's red lead to the positive terminal of your battery.

What is a Charging System? The voltage regulator can be mounted inside or outside of the alternator housing. If the regulator is mounted outside (common on some Ford products) there will be a wiring harness connecting it to the alternator. The voltage regulator controls the field current applied to the spinning rotor inside the alternator.

- Use a voltmeter, and check the voltage between the narrow opening and the ground opening. It should measure about 110-125V. Measure the voltage between the wider opening and the ground. It should be zero.

- Connect the positive (red) test lead of a voltmeter to the car battery positive (+) terminal, and the negative (black) test lead to the + terminal of whichever headlamp filament (beam) you're testing -- use the bulb farthest away from the battery. Your voltmeter will give a direct reading of the voltage drop.

How to Properly Check the Juice in Your Car Battery Then put a voltmeter across the battery posts while cranking it with the key or an external remote starter button. Crank for 15 seconds (no longer); the battery voltage should remain 9.6 volts or above. (These are GM specs for a battery at 70 F; your mileage may vary.) Another way to check is with a dedicated battery tester that has its own internal resistor pack and voltmeter.

BMW To check hot, ignition, lights, dimmer, use a test light or voltmeter. To check speakers use test radio. To check speaker polarity (assuming you don't have a polarity tester): Touch (for a very short period of time) one wire to the positive side of a 1.5-volt battery (any size), and the other wire to the negative side. If speaker pops out, then polarity is correct. If speaker pops in then polarity is reversed.

How to Test an Alternator Test the alternator with a voltmeter. Alternator test with a voltmeter. If it's in the range, it's good. Connect the meter leads to the battery terminals and look for 13.8 to 15.3 volts (engine running, lights and accessories off). That means the alternator is pumping out the juice.

- To test this you need to do a full field test on the alternator. Just supply battery power to the alternator bypassing the regulator and measure it's output. If the output is in the neighborhood of 14 volts, then the alternator is fine and it's the regulator's fault. If the alternator's output is over that than it is the cause. But it does sound like the regulator is the problem.

Any way to load test a car battery without an actual load tester? Okay, now turn on your high beams this is your load observe the voltage if it's below 9.6V your battery is weak below spec, replace it. Or, you can bring your car to autozone or advance auto parts and they will do the more accurate test for free.

- The alternator has a regulator that tries to keep the voltage across the battery at a steady 14.4V (the optimal voltage to recharge 12V car batteries). It does this by regulating the amount of current flowing to the field coil.

How to Check a Car Battery This is not the setting you want, unless you plan on testing household appliances. So, save AC for the washing machine. Step 3: Read the test results. Check the voltage reading on your screen. Battery voltage readings are as follows: 12.66 volts = 100% charged. 12.45 volts = 75% charged. 12.24 volts = 50% charged.
