The most likely problem is your alternator, but you can check with a volt meter to ensure that is your problem. Start your truck (use a battery charger or jump to start it if you need to) and put your meter on the battery post's. If your reading 13volts or so your alternator is working and maintaing voltage, however if your reading starts dropping to 10 or less(may take a few moments to drop) then it's probably your alternator. You can also check your battery's voltage before starting your vechile, if the voltage increases after you start the vechile then it seem to be charging. Alternators can be repalced somewhat easily, it's only two bolts however you do have to remove the fan belt, and re-route after installing the new alternator. If you have some expirence working on cars you can do this yourself in your driveway.

Hope this helps

How do you know if alternator is bad on a 2006 hyndai sonata v6


Using a volt meter check the voltage at the battery with the vehicle running. There should be more than 13.5 volts. If it is more like 12 volts or less that the alternator is not working or there is an open between the alt and the battery. The most common cause of the battery light is a bad alternator.

Replaced alternator twice,battery light come on after 1 day and pulls battery down.


Hi.
There's no good news here !
First charge the battery, start vehicle , allow to idle (put volt meter on ) battery voltage should rise . Turning on headlights and observing rise in heater motor speeds or interior light illuminaion on accelleration should be observed ! If the battery voltage does'nt rise , replace alternator (not what you want to hear but has to be done )
So good alternator and running , everything ok. if vehicle fails to start after this, check battery condition and possibly replace.
Good Luck

I have a 95 isuzu rodeo v6. it was having trouble starting. today it would not start. battery/brake light came on. found out starter was bad, replaced it. the light is still on and after replacing starter...


possibly wrong termination of wires @ alternator.

to drop off a battery cable is one old and reliable way to check charging system. if belts are tight and wiring is correct it is time to put a meter to alt and verify output voltage is within acceptable ranges.....

I have a 1990 ford f150 with a 4.6 6 cyl.. Went


You need to pull fuses to see,but it can still be the alternator,with a bad diode allowing the drain,remove the negative battery cable from the battery,then buy a test light,they are cheap,clip one end to the negative battery cable,and touch the tip of the test light to the battery post,and the test light will light up,cause there is a draw on the system,make sure the doors are shut,and the lights are off.Then unplug the connector on the alternator,if the test light light goes off,the alternator is the problem,if not,remove the dome light fuse,and start pulling fuses one,at a time,and putting them back in,as you go,if you pull a fuse,and the test light light goes out,that is the circuit that is drawing the voltage from the battery,leave it out,and hook cable back up,and see what does not work with the fuse still out,and that will be the problem,please rate if this was at all helpful,thank you.

The battery light came on and the battery was replaced. The alternator was also checked and determined to be ok. Now the battery light comes on and the slternator shows as charging at about 14-15 Volts any...


check the battery with a volt meter. Place the probes from the meter inverted which means positive from the meter to negative on the battery and negative from the meter to the positive one the battery. MAKE SURE YOU STE THE METER TO THE DC & NOT TO THE AC MODE BEFORE YOU TURN THE METER ON. Now start the engine and see if a reading shows of 14 - 15 volts. If so the diode is bad in the altenator. The diode suppose to keep the current running only one way. If the current is running both directions the altenator does not charge the battery completely and the battery light will come on this way also

1991 ford ranger battery light


bad battery module for the light or a dieing cell in battery

batterys can be tested and wont show a dead cell at all but you will be told that the battery good
most batterys are refurbished batterys sometimes getting the luck of a good battery is 50/50 chance

heres a way to test the battery and alternator at the same time
start vehicle
disconnect battery positive post
if vehicle dies the alternator is at fault if vehicle doesnt die its the batterys life dead cell
