It stays on until reset even if proper repairs completed. Some will reset if you disconnect batt for a while. if yours doesn't, any shop with a code reader can plug into your dash and reset for you.

Can the voltage regulator stop the motor from firing on a 1990 dodge 250 van?
No, the voltage regulator determines the alternators output voltage. That's all it does. If the regulator fails the battery level can drop to the point that there will not be sufficient charge to start the engine, but the regulator will not directly cause the engine to not run.
Why is your dodge stratus not charging a new alternator?
Cars don't charge alternators; alternators charge cars. If your new alternator isn't charging, it could be your battery is bad or your battery connections are corroded. Another thing it might be is your voltage regulator. Many alternators come with built-in voltage regulators, but if your system has a standalone v.r., it could be bad too. Finally, if your 'new' alternator is actually a refurbished or rebuilt one, it could be a bad rebuild. It happens.
Lincoln mark viii 98 you replaced the altnernator and now your car wont run unless you charge the battery yourself what is the problem?
With the engine running, test the voltage of the battery using a voltmeter. You SHOULD be getting anywhere from 13.5 to 14.5 volts if the alternator is functioning properly. Turn on the headlights and rear window defroster and make sure you can hold the voltage level (you'll need someone to keep the engines at about 2000RPM's. If the alternator isn't producing sufficient voltage, you either have a faulty alternator or the replacement was not connected properly.

Why will 1995 Honda Civic DX only start when jumped with jumper cables- it won't start with a jumpstart pack that is fully charged- Ran for 30 min to charge and no start- Alternator or ignition switch?
If it were the ignition switch, the vehicle would not start even with a jump. The battery is either not holding a charge or the alternator is not providing the charge to the battery. You can have the battery and the alternator checked (usually free of charge) at an auto parts store,

Where is the location of the voltage regulator on a 2008 dodge ram 1500 truck?
The voltage regulator for the alternator is in the computer. If the voltage regulator in the computer does not work, you can add an external voltage regulator and then your battery will charge normally. Make sure to check the ground on the computer. If the ground is bad on the computer, then the computer will not regulate the voltage to the alternator properly.
What component recharges a vehicle's battery?
The alternator, in cooperation with the voltage regulator and the charge relay.
Can an alternator that has a built in voltage regulator show good when the regulator is bad?
If the regulator is bad, the alternator would have a low charge or a high charge or no charge at all. With a good battery that is fully charged (12.68 volts) and the engine warmed up and idling with no accessories on, you should get a voltage reading at the battery of 14.2 v (plus or minus .2 v).
Why alternator will not charge battery on 2005 ford focus... New alternator new battery replaced already?
