HEy guys my truck wont start....I noticed 2 days ago the battery was dead...I thought maybe i left a light on or charged my phone without the truck being on but now i think its something else....I got a jump and i have a battery gauge on my truck and watched it get charged as i drove home.......i went out to start it today and its completely dead again....Im positive the lights werent on etc...What could be draining my battery when its turned off....Please help

 

do you have a sound system in the truck? a radar? anything new installed?

 

No none of those....But i have been hearing a clicking noise under the passenger side dash when i have the air turned on....But electronically ive had nothing done!

 

Well **** noone can help....My question is since i know the alternator is working because when i got the jump the battery was getting charged as i drove home....If it was a bad battery wouldnt it still hold the charge or would it loose the charge from the alternator...Or does something have to be draining the battery...Should i just go buy a new battery???

 

Go to an auto electrician, unless you can do comprehensive battery and alternator tests.....it is possible for a bad battery to do this, and it's also possible for an alternator to charge a battery, then drain the charge if there's diode problems, for example. A proper test by an electrician shouldn't be that expensive.

I guess check all your fuses too....and if your ignition switch is turning off properly...

 

THanks alot ill check into it

 

Just take it to autozone or somewhere similar and have them test the battery and the alternator.

 

battery wasnt the problem...put a new one in and shes dead again...probably the alternator diode?

 

Hmm either something alternator related, or something draining the battery in a massive way....if you keep the battery disconnected, you may be able to save it (although fully draining batteries kills them) - I suppose you could reconnect battery after charging it separately, then feel all the fuses and see if one seems particularly warm, that might indicate the circuit that's draining it, if it isn't the alternator....or you could go to the auto electrician who will be able to diagnose it probably faster than we can...

Hope it's something easy, anyway.

 

Thx for the help....The alternator was fried...the stater was burning could smell it just now...Got a new alternator and plug put in....Hopefully it the last repair i have to do!! Thanks

 

Any Auto repair can test your battery it takes about 5 seconds - the machine is usually under there counter - test under-load - test for bad cell - just take it somewhere , they will test it right away - it increases they chances on selling you a new one, lol..
