Remove Your Negative Battery Cable. Make Sure Everything Is Off In The Car. Also Remove The Hood Light Bulb {the light that comes on when you raise the hood }. Connect A 12 Volt Meter, Or A Test Light ( Most Parts Houses Have These Around $8.00 } Between The Battery Negative Terminal And The Cable End. If The Light Comes On You Have Someting Using Voltage. You May Have A Grounded Wire Ect. You Will Have To Locate The Source Of This Until The Light Goes Out. When It Does, You Should Be OK. Note If Meter Don`t Show Voltage. Have Your Battery Tested Again.
There are a few things that could cause this problem. It could be the wiring to the alternator, the alternator solenoid, or the wiring.?æ
Have you had the alternator tested? Often a bad internal diode can drain the alternator overnight.
Your battery does not supply electrical power to the vehicle it simply stores it. The alternator is what recharges (replenishes) the power used during cranking. You need to have your charging system checked to verify the alternator is working and at the same time you need to have the battery diagnosed as draining your battery completely repeatedly can cause premature failure.
yes if one of the wires was getting an earth from the alternator cover or rubbing off the engine the battery light is really an alternator light warning you that the alternator is not charging the battery
The cause could be several factors. one is the battery charged. your startercould be bad or the alternator decharged your batter and your alternator is bad.When you turn your ket you should hear the ignition switch click that means it's fine. if your battery is charged and you turn you key and the lights dim you probably have a bad starter.
No battery.
The answer is no . The battery starts you vehicle , the alternator charges the battery so if your alternator is bad your battery is not receiving a charge which will cause a "no start" condition.
Often it's an alternator diode. Check the battery first. When batteries start to go bad they can often start to discharge over a couple hours. Take it to an auto parts retailer and have them test the battery and alternator for you. I had the same problem with my '92 Windom (ES 300). It was a faulty trunk mounted CD changer that was draining the battery.
You may have a short circuit somewhere that is leaking current to ground. Or you could have a bulb or accessory that is using current even when the vehicle is turned off. Improperly installed aftermarket stereos & amps are a notorious cause of this.
Yes
Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
Possibly a bad alternator. The Alternator charges the battery when the vehicle is running. If the battery is not being charged this could cause the vehicle not to start.
