What else can I help you with?
Can an internal voltage regulator be replaced on a 1996 jeep grand Cherokee or does the alternator have to be replaced?
The regulator is in the engine computer not the alternator.
Where is the voltage regulator in a 1997 Jeep Grand Cherokee?
The engine computer is the voltage regulator in a 1997 Jeep Grand Cherokee.
1997 jeep grand Cherokee alternator test What is the best way to test the alternator and the voltage regulater?
use a voltmeter A fully charged 12v battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 volts with engine running
Does the 1994 Cherokee jeep sport have an alternator light on the inside panel?
When my jeep cherokee alternator went bad, the check engine light came on and I didnt have a clue what was going on until my volt guage was reading in the red zone. When I replaced my alternator, the light went off. So in my opinion i wouldnt consider the check engine light as a alternator light.
Alternator not charging 1989 Jeep Cherokee Laredo?
best way to tell if the alternator is charging is to unhook the battery with the engine running, if it shuts off then you know you have a bad alternator, i wouldn't recommend this with newer vehicles due to the fact you could hurt the computer but an 89 i wouldn't worry about that so much, good luck!
Engine staled while driving and the battery light came on then went off and then your check engine light is on would it be my alternator or battery that needs to be replaced?
your Alternator
Does leaving the car on but not driving it anywhere drain the battery?
If the engine is running, then no. The alternator constantly keeps the battery charged.
Would a bad alternator cause a car to die while driving?
If the alternator fails, it is no longer keeping the battery charged and your engine is running on nothing but battery power. Once the battery runs down, your engine will no longer run.
Does driving with the lights on increase fuel consumption?
(no it uses the energy from the car battery not the energy made by the engine)Yes it does increase consumption because the battery has to be recharged by the power of the engine driving the alternator or the dynamo
Why does 1999 Jeep Grand Cherokee engine switch off after being jump started?
This usually means that you have a dead battery. Either from a bad battery, or a bad alternator.
Does the motor charge the battery when you run the engine?
No, the alternator recharges the battery. Of course the alternator is turned by the engine.
Why would a 2004 envoy battery drains while driving?
Alternator is defective or the battery has a dead cell and will not take a charge. Check the voltage at the battery with the engine running. You should have between 13.5-16 volts. Anything less and your alternator is bad.
How do you get the alternator to turn over?
The alternator is run by a belt connected to the engine. When the engine is running the alternator is turning. The alternator is what produces the electrical current that charges the battery & powers everything electrical while the engine is running. the battery is mainly to start the engine.
What could cause engine to try shutting down while driving and battery going dead overnight if battery and alternator have been replaced?
Sounds like the engine is using the battery as the source of power instead of using the alternator. The main job of the battery is to give power to the starter that "starts" the engine. Once the engine is started the alternator kicks in to maintain power throughout the vehicle, as well as keeping the battery strong. But if the alternator isn't working, the engine will get it's power from the battery. And without the alternator keeping the battery strong, the battery will die. Note: between the alternator and the battery, there is a voltage regulator, this make sure that the battery only gets the power it needs. Oh, one more note, here's a way to tell if the alternator is working properly. (Start the engine, while it is running remove one of the battery cable for just a few seconds.)if the engine stops, then you have an alternator problem still. Check your wires. Or replace the unit. for more answers. email tjjjlong@aol.com A constant 12 volt drain on the electrical system, even when the car is off
Is the regulator on a Cherokee 1990 built in to the alternator?
No it is in the engine computer.
Does a 95 Oldsmobile cutlass ciera with a 3300 v-6 need the alternator to start it?
Yes, a 1995 Oldsmobile Cutlass Ciera with a 3.3L V6 engine needs a functioning alternator to start. The alternator charges the battery while the engine is running, but if the battery is fully charged, the car can start without the alternator working. However, once the engine is running, it will rely on the alternator for electrical power and to keep the battery charged. If the alternator fails while driving, the vehicle may eventually lose power and stall.
Why does the battery light come on while driving even though the alternator is charging the battery?
The alternator may not be charging it enough. With the engine running at an idle check the voltage at the battery with a DC digital voltmeter. It should read from 13.5 to 15.5 Volts. Anymore, or any less, and the alternator is suspect. You might also have a defective battery.
