2005 escape engine dies with battery light on?
Bad alternator- not charging battery enough to keep vehicle running check with a volt meter A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Engine dies repeatedly possible bad ground?
Alternator? check your volts on the battery while running. it should be at 13 to 14
My '91Mazda 323 dies while driving It starts fine with a boost but dies soon after Help?
Probably need an alternator. Check your battery voltage with a multimeter, without the car running it should be around 12.5 volts with engine off. Start the car & check the battery voltage and if the alternator is charging properly it should be 13.5 or better at the battery. If not check the power terminal at the alternator itself and if only battery voltage (12 or so volts, same as battery) is there then the alternator is not charging.
Why does the ford bronco shut off when you disconnect the battery?
1st there must be some reason as to why you are doing this. I don't feel it is ever a good idea to remove the battery cable while the engine is running. But if you must know, your engine can only keep running while it has 12 volts going to certain areas... such as coil and distributor. If it dies when you remove the battery then I would guess that the alternator is not working, which may be why you were testing this in the 1st place. A good test for your alternator is to put a volt meter across the battery and see the volts, then start the engine and see if the volts increase. If they dont and the volts are dropping then the alternator needs to be checked out.
Volvo 1991 240 automatic that runs for while then the battery dies Reading 12v off the alternator wires while running Last time it died radio went on and off?
Your alternator is not charging. When a vehicle with a 12 volt system is running, the alternator normally puts out at least 13.5 to 14.5 volts More than that, the battery is overcharged. Under that, the alternator is not functioning and it is running only off the battery voltage.
If the car battery dies because the door was left ajar will just boosting the battery and running the car be enough or do you need a new battery?
It should come back after running the engine if the battery is good.
Is there a way to determine whether it is your battery or alternator that needs to be fixed in a 2001 Bonneville?
If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good. If it stalls and dies as soon as you unhook the battery then the alternator is not good.If you can get your vehicle started you can then un hook the battery while it is running and if your vehicle stays running then your alternator is good. If it stalls and dies as soon as you unhook the battery then the alternator is not good.
How do I know if if my car battery or alternator is dead?
Fully charge the battery Check with a voltmeter (should read approx. 12.8 volts without engine running) With engine running and good alternator reading should be 13.8-14.2 if the battery is dead the car wont start. replace the battery (preferably with a new one) run the car and if it dies or wont crank again its the alternator (or possibly the alternator belt is slipping)
How do you determine if alternator is bad on 2001 Ford Escort zx2?
One way is to check the output on the alt wires with a multimeter and make sure it is putting out at least 12 volts. The easy way is to remove one of the battery cables while the engine is running. If the engine keeps running the alt is fine, if the engine dies, then the alt needs to be replaced. If the alt is bad the vehicle will run while the battery is charged, then dies when the battery goes dead because that is all that is powering the engine.
New battery but bike won't stay running 1993 Honda Shadow Will run when hooked up to jumper cables but dies as soon as it is taken off?
First, make sure the battery is fully charged. Even if it is new, check it with a volt meter to make sure it has at least 12.5 or better volts. If not then charge the battery at 2 amp'2. till fully charged. Then try with fully charged battery. Does the engine start? If so, check the charging system on the bike while it is running, without the boost. You have to have at least 13.5 to 14.5 Volts. If not,and you get only the base volts of the battery say 12.5 or less most likely the Stator is defective and will have to be replaced, or possible the regulator. Hope this helps.Good luck
If you disconnect your battery will your 92 Mercury Sable stay running?
If your alternator is good it should stay running until your engine dies from no fuel.
How do you tell if Alternator is bad?
Get engine running. While the engine is running disconect the POSITIVE termninal from the battery. If the engine dies, the Alterntor is bad.
