More then likely a defective alternator, with volt meter, check voltage at battery, that will be alternator output voltage, should have a reading of no less then13.0 volts, also alternator sit on top, check voltage also at back of alternator on the big wire, should also have no less the 13 volts, if less replace alternator.

Battery light is directly connected to the voltage regulator of the alternator. If it is on, it means you have a bad alternator/regulator combination meaning a new alternator is in order.

This is a very common problem. That's why they have a light for it.

Wish you luck on this one.

My car is turn on charging light


the charge light is worked by current flowing from positive to negative when the ignition is on and then from positive to negative when the alternator is charging. As the alternator current is greater than the battery current then the opposing current flows puts the light out as there is only a very small current that will not illuminate the light. For the charge light to come on then the alternator would have to be really overcharging the battery and you would know this from the boiling sulphuric acid smell and a really hot battery. have an accredited auto electrician check out the system as the so called battery may not be as good as you think. check that the terminals on the battery and the battery posts are shiny clean and tight. Check that the drive belt is in good condition and properly tensioned.

Yes, a slipping belt can certainly affect alternator output. Squealing could be a bad belt, but check all the pulleys for the belt for roughness or wobble-bad pulley.

Car dies and battery light comes on


If the light is on when car is running, the alternator is still not working. Check your power distribution center near the battery for any fuses out. Maybe there is an alternator fuse.
Is your battery good? A completely dead battery may not take a charge from the alternator. It needs to be charged off the car. Have it load tested at a parts store to see if it's good.
Is your alternator belt tight? A loose belt won't let the alternator work to capacity.

Riding home all of a sudden the red icon of the battery came on (service Charging Sys/battery not charging) what does that mean? tried to crank however the radio, lights /dashboard al lights up but sound...


The battery could be the problem. Best to take it out and have it tested. But on the other hand, if the alternator isn't putting out the voltage to keep the battery charged, it will also give you a charging fault. From your info, I feel the alternator may be going out. If the the alternator is going bad it will or can make the battery bad. So get the battery checked out first to be the easiest and it's free to check.

1985 toyota pu charge light on


Your alternator is not producing current to recharge the battery. Check to see the belt is on and properly tightened. Make sure your battery connections are clean and tight. If the belt and battery are good, remove the alternator and have it checked for output. Most likely will need to be replaced.
