Why new battery and alternator won't hold a charge when car is running?
The alternator does not hold a charge. It charges the battery. If it will not charge the battery then either the alternator is defective, battery is defective, or the connections are corroded or loose. You should read 13.5 to 15.5 volts at the battery with the engine idling. Check it with a DC volt meter. If you get less the alternator is defective. If you get much more the voltage regulator is defective.
Is it the battery or the alternator that is bad on a zx7r that shows 11.77 volts while idling at 3000?
Unless the battery is shorted or sulfated and will not take or hold a charge, most likely the alternator is bad
What does it mean when your Jeep Cherokee rattles when idling?
something is loose
Can an automobile battery be recharged just by driving it a long distance?
Yes, if the alternator is functioning and you are not loading the charging circuit (using as much charge as the alternator is putting out so the battery receives nothing). Please note that "Idling" to charge the alternator normally does not work as the alternator is not turning fast enough to charge the battery, it only maintains the status quo for energy usage.
How hot is normal for a new alternator to get when idling for an hour after replacing it and the battery on a 1993 Buick Skylark?
They will run somewhat hot while charging; if you put your battery in discharged however, that makes the alternator work much harder. A alternators job is to maintain the charge in a battery not to charge a discharged battery.Keep a eye on it, it will probably be OK once the the battery is topped off.
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).
My 1987 Lincoln town car has a problem with the charge system. it runs but doesnt charge the battery it just drains it if its parked and idling. bought the car for 500 and this is the only problem.?
One of three things: 1) The battery has a dead cell and will not hold a charge - have the battery checked free at a local AutoZone or similar auto parts store. 2) The alternator and/or components is/are faulty and will not provide a charge - have the alternator checked free of charge (same place as above). 3) The belt is loose or worn - if loose, tighten; if worn, replace.
Does the alternator charge your battery when the car is idling?
Yes and no. Yes: The alternator will charge the battery any time the engine is running (even at idle) if the battery's voltage is below the threshold (usually around 12 volts) so that the voltage regulator triggers the alternator to generate power (around 14 volts) until the battery is charged up. No: If there is not enough consumption of power, the battery may be charged enough and the voltage regulator will not trigger power generation.
What does it mean when the odometer flickers as high as 5 mph when the car is in park and idling replaced battery due to old and wouldn't always start however will not hold charge.?
Have it tested and also have your alternator tested.
Symptoms of Ford Escape alternator failure?
unstable idling and battery indicator lights on.
If you reverse polarity on the battery and the fuses are fine and the alternator check out ok why would an 81 Toyota pick-up wont stay on whithout having your foot on the gas pedal?
When the truck is idling at low RPM, the charge supplied by alternator is not sufficient to run truck and charge battery of reverse polarity. Alternator expends majority of amperage toward charging (which never takes) and increase in RPM is required to spin alternator fast enough to accomodate ignition system and charging system in unison.

We cleaned the battery terminal and now the car will not idle properly?
Cleaning the battery terminals had nothing to do with the engine not idling properly. Just a coincidence.
