Best Answer

If the battery continues to go down even though the system is charging it normally indicates there is an amperage draw. to test it without any meters; disconnect the negative battery cable and observe when you touch the connector to the battery. If there is even the slightest spark, you have an amperage draw and that will run your battery down.

How do know when to get a new alternator?

If it is not keeping the battery charged then it is defective. Start the engine and connect a volt meter set on 20 Volts DC to the battery posts. Red probe to positive and black to negative. You should get a reading of from 13.5 to 16 volts. Any less or more and the alternator is defective.


How do you check a battery is charged?

Take a DC volt meter and check the voltage at the battery. Red probe on positive + terminal and Black probe on negative - terminal. If it reads 12.6 volts it is fully charged. 12.4 and it is 75%, 12.2 and it is 50%, 12.0 and it is 25% charged. Less than 12 volts and it is considered a dead battery.


Why is your Battery not charging after replacing alternator on 95 ford probe?

Chances are you drained your battery when your alternator failed to maintain your cars regular running functions. You should take the battery to your local auto parts store, they should be able to test it for free.


If the alternator is good but the battery isn't charging in your 95 Probe SE could the main circuit relay keep the battery from charging?

No, take the battery out and bring it to an auto part store and they can test it.


How do you check battery state of charge with voltmeter?

You must have a digital volt meter. With the ignition switch turned off, set the digital voltmeter to 20 volts DC. Put red probe on positive battery post and black probe on negative post. A 100% fully charged battery will read 12.6 volts. 75% charged will read 12.4 volts. 50% charged will read 12.2 volts. 25% charged will read 12.0 volts.


Where is the voltage regulator in a Ford Probe?

In the alternator. Have to replace the Alternator.


Is the test light supposed to light up when you use the ground from the battery or only light up from the positive side?

If the alligator clip from the test light is attached to the negative post of the battery it will light up whenever the probe end touches a positively charged circuit and likewise if the alligator clip is attached to the positive terminal of the battery the test light will light up when the probe end touches a negatively charged circuit


Does it mean that your battery is no good when the light flashes when driving BMW?

Generally when your light is flashing it is indicating that your battery is not charging properly. It usually means that your battery, alternator or alternator belt need replacing or adjusting. Easiest thing to check is your belt so you can start there, make sure it is not loose or frayed. Next, disconnect the battery terminal while your car is running, the alternator alone should be able to keep your car going. If the car DOESN'T stall then it is most likely that your battery that is no good. If the car DOES stall then your alternator is defective. To properly test your alternator with a voltage meter attach the ground to (+) positive probe to the main power feed on the alternator and attach the (-) negative probe to the (-) negative battery terminal or ground it on a piece of the car's frame. It should read somewhere around 10.0 - 15.0 amps. Anything less will be insufficient to turn the engine over. If none of these seem to be the problem then you have an electrical short somewhere between the battery and the alternator. ADDITIONALLY, i'd like to point out that many auto part stores will test your battery and/or alternator free of charge. So don't be afraid to stop there and ask for help.

How do you replace the alternator on a 1991 Ford Probe GL?

If you're mechanically inclined I recommend you buying a Chiltons or Haynes repair manual for the 1991 Ford Probe. Most provide the info on removing and reinstalling the starter. Also you might check your local library/s for these manuals. , EzForJesus the alternator is located behind the engine. the passenger side axle shaft must be removed in order to get the alternator out. make sure you disconnect the battery first.
