Question about 1996 Jeep Grand Cherokee

3 Answers

When the Jeep was new the volt meter read 14 volts....now the volt meter reads 13 volts with a one year old battery. Since the battery is a 12 volt battery should there be any concern that the volt meter reads 13 volts rather than 14 volts?

Generally the standard voltage should be 13.5 to 15.5 depending on the load that is being put on the vehicle and age of the battery an older battery may require more voltage to charge. Unless the voltage drops below 13 you are probably ok.

Your voltmeter display what is called dynamic voltage... this is the power available from the alternator output. 13 V does sound a little low, but to know for sure you should have an output test performed on the alternator (the amperage reading is more telling then the voltmeter reading on your dash) and have your battery tested. that being said, 13V is not going to leave you stranded anywhere, but should be checked out before it gets worse and does! good luck!

It needs to be looked at,hook a volt meter to the battery,and start the engine,turn the ac on high blower,and the head lights on,the alternator should be putting out 13.65 volts to 14.25 volts,if it is any lower than this,replace the alternator,now,if the reading is not the same as in the vehicles volt meter,then the cables,positive and negative need to be replaced,the cables get old,and corrode on the inside and break down,they do not carry the current as they should.Shuold you decide to replace them,go with a larger diameter cable,both positive,and negative.

Disconnect battery while car is running. If car dies altenator is bad. With car not running check battery with volt meter. Should read 12 to 12.46 without engine running. Start car and check battery with volt meter, should read 13 to 13.50. If less than 12 with engine running then altenator is no good.

Battery discharges in about 3 days if not run.


it may have deffective diode on the charging system(the alternator). 14 volts is an over charge in a battery. ampere reading must be on what the battery designed.

When I try to start my car, the battery turns on but my engine won't turn over. What does that usually mean?


My friend, the battery is on all of the time. You don't turn it on and off. If the car fails to start, it could be a problem with a safety interlock system, a failed start solenoid or a weak battery. I am leaning toward a failed start solenoid in your 14 year old car. There is a safety switch on the clutch if manual shift, on the gear selector if automatic and possibly other places as well.

With a volt meter, place the red probe on the starter side of the solenoid (the cable opposite the battery side) and the black probe on ground. Of course you will set your meter to DC at some voltage higher than 12 volts. Have someone turn the key and try to start the car. If you get a reading of 12 volts, I would suspect the starter. If there is no reading, I would suspect the solenoid. While you have the volt meter out, check the voltage of the battery. It should be at least 11 Volts and maybe as high as 13 with the engine not running. With the engine running, expect to see as high as 15 1/2 volts.

Battery light is on


The battery voltage needs to be checked.Also if battery is very old and not replaced for very long, then just get the battery replaced.Approx battery life is 3 years.If its very old battery then try new battery. But if battery is new and still battery light is on,. then either battery terminals are dirty or not connected properly or the battery voltage is low.Get the battery re charged to proper voltage.The exact battery voltage of charged battery is 12 volts..Re check and confirm with voltmeter. This should help.Thanks.Helpmech.

There's a light appear a battery symbol in the dashboard and if i booster it it will start then after 15 minutes the engine will shut-off,i think the alternator is out,can you help me please to...


yes sounds like a alternator problem check battery voltage with volt meter a good battery should read around 12.5 volts start car with car running should read around 13 to 14 volts if it doesn't read 13 or 14 volts your problem is the alternator or wires going to alternator (more than likely alternator)

1993 Grand Prix, 3.1 L Engine, when I start it up voltage regulator shows 12 volts , when I turn on the headlights it goes to 14 volts. I have checked the alternator & starter. Both ok.


Have your battery load tested to make sure it's OK...14volts is the high limit for charging...If reading dash gauge, it's better to use a volt meter directly connected to the battery to get more accurate readings. What is the voltage with headlights and heater turned on (should be no less than 13 volts) I suspect that your battery may be at the end of it's service life but accurate testing is necessary to verify this!!

1991 ford ranger battery light


bad battery module for the light or a dieing cell in battery

batterys can be tested and wont show a dead cell at all but you will be told that the battery good
most batterys are refurbished batterys sometimes getting the luck of a good battery is 50/50 chance

heres a way to test the battery and alternator at the same time
start vehicle
disconnect battery positive post
if vehicle dies the alternator is at fault if vehicle doesnt die its the batterys life dead cell
