How to change battry - Cars & Trucks

If test light is a 12 volt light tester AND ILLUMINATES BRIGHT it shows that a component is actively trying to complete a circuit and yes drawing power causing a drain on your battery, now if test light illuminates low, possibility could just be ecm memory or antitheft system active . either way this test should only be done with a 12 volt test light as if you use a 5 volt (computer friendly) tester , false light will have you chasing a ghost. trust me. that trick helps by checking for parasitic draws a 12 volt tester does not illuminate when keep alive memory voltages are present . those voltages are not enough to drain over night. good luck

The battery is not charging. Check the drive belt is not slipping, otherwise it could be an alternator fault.

does it stay on when you have driven the car for a few minutes? if you did not drive it , try that

Have you checked the voltage at the batry when running? Sounds like alternator is not working properly. The battry is only used for starting, once started the alternator runs all the accesories & charges the battry. If not chargeing the vehicle will **** battry power. You may have a good battry surface voltage but a bad battry. The battry should be load tested as well.

Check alternator output voltage. Probably overcharging.

check to see if the battrie is full charge most likely the battrie is dead charge it for two or three hours if it dosent start the battrie is probley bad , clean the battrie termnails or if you have jumper cables jump it if it starts let it run for 20 minutes shut it off and try to start it if it dont start most likely the battery is bad

Give some more details of the problem.

its easy open ur car bonit & c if there is battry there ,then lose ur battry clips & make some space for heand & then first pull ur light holder then rubber cover then there is lock on bulb open it & then finally with care pull up the bulb & replace it .
again same prossitur put the bulb or tube again then put lock on it then rubber cap then holder...ooh dont forget to tight battry clips again.....
its thats much simple.....tc

i'd have the battery and charging system checked

id go with changing the alternator...if its pushing too much back to the battery it will cause you to lose another batery
