Alternators
Car Batteries

What could it be if your 2 liter Vectra cuts out whilst driving and when it restarts the battery charging light is on and sometimes it is very difficult to start but you have replaced the alternator?

the battery could be the cause of slow starting battery light on. the cells inside break up depending on age year. also has the mulit rib belt fell off, there may also be a problem with your fusebox. have u had an alarm fitted recently, is it a new shape-old shape vectra.

alternator needs to be replaced. battery also might be a problem due to the alternator not charging it

Alternator is not charging. Have it tested and/or replaced.

If the light remains on then the system still isn't charging as it should. Check the plug on the alternator and also that the wires to the alt have a good connection.

Sometimes, but not always, the alternator will whine loudly when it's malfunctioning.

There is something wrong with charging system. Have the alternator checked and replaced if necessary.

Could be a bad signal sent by the computer or the alternator is not charging to full capacity. Have someone check the charging amps on the alternator.

94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located

New Alternator BUT Warning Light Still Stays OnMaybe there was nothing wrong with the alternator you replaced, and the problem is somewhere else in the charging system!Although possible, it is highly unlikely that a new alternator would be defective.

It depends on the year of the vehicle. Newer (late 60s/early 70s on) had "internal regulator alternators", so the alternator needs to be replaced. Older cars have a regulator, usually mounted on a fender well, the fire wall, or the radiator support which canb be replaced independently of the alternator.

check the alternator. Use a digital multimeter and with engine running you should have 13-14 volts at the battery. If less than 12.5 Alternator is not charging Also check the amperage the alternator is putting out.

we have a 460 ford in our jet drive boat. recently we have replaced the fotor and the alternator is not charging we are not sure if it is connected properly. It is currently connected with two wires. What Do you recommend?

User Avatar

Your car should produce about 14.4 volts from the alternator when the engine is running. If it does not produce anything over 12 volts, your alternator is not charging and you need to get it repaired or replaced.

It means something is wrong with your charging system. Can be a loose of corroded battery cable, defective alternator or a battery with a dead short.

Well it could be the external regulator on the right side of the engine compartment or a bad alternator . First I would have the battery checked to verify the battery is good but only after fully charging it , then try replacing the regulator first because its cheapest and if the alternator is in fact bad it should be replaced with the alternator anyway. If the regulator doesn't help then It's probably safe to assume it would be the alternator. I've had a loose plug on the alternator also that would keep it from charging, you might wanna check that and all your connections first.Hope this helps.

Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alt belt.

User Avatar

could be the alternator or starter sounds like the alternator if the battery is gone flat get the alternator tested at auto parts or garage jump charging the battery might get you out of trouble for a bit

User Avatar

if its not charging make sure all your connection are plugged, simple way too test your alt. is start the car remove the pos+ive terminal and see if it still runs if not bad alt. and you will need it replaced. This procedure is not recommended. It can damage a good alternator.

User Avatar

One possible cause is a defective alternator, Have the charging system checked.

User Avatar

The battery light can come on due to a low charging voltage. Check the alternator for full output, and make sure that the alternator belt is not slipping.

User Avatar

It is probably a bad voltage regulator. Sometimes they are located in the alternator and can go bad in a new one. On Ford vehicle the voltage regulator is separate from the alternator.

This is not a battery problem. Your charging system, the alternator, is not putting out enough juice to charge the battery until you reach 4000 rpm. Have the alternator and charging system checked.
