You can go get a parasitic drain test done on your truck but that would only confirm what you believe. It in order to find out what is remaining on you would have to hook up a scanner to see whats staying on that should not be.

U most likey are not getting voltage out of alternator to the battery , check the large wire coming out of the alternator to the battery it should be 13.75 to 14.25 output if not it may be a heavy fuse like on a 99 tahoe u can take a 6 gauge cable and run from bib post on alternater to the positive on battery. some ford and some gm have a plug in wire harness that has this wire already in the harness,just go to the parts store and ask for a alternator harness to replace it with .this is the only explanation for ur problem.any questions feelfree to e mail me at roniecon@gmail.com

My 2012 hyundai sonata battery will drain dead after 2 days when I don't start it, what could be the problem? I have to jump start it and if I drive it everyday its fine.


it can be a number of problems one can be you have something is staying on it can be a light in the boot,you alarm is wired wrong or a radio is not off or it can be the battery no good. By jumping the car with a jumper leads can damage the battery, or you alternator is not charging good. First to check your alternator you will need a volt meter and place the negative from your meter to the negative of the batter and the positive to the positive and start your car. If the reading is 14.3 V to 14.8 V your alternator is good than the problem it can be any of the other things that I indicated

I am trying to do this from home have no testing equipment and do not know what iI need to test. I drove the car on Sautrday had not one problem. Tried to start the car on Sunday and I had absolutely no...


Hello,

Based on your problem, that I read fully twice, based on ALL THE things that are dead, this is positively a battery charging system problem.

Meaning this, Sense nothing works including head lights, which would work most likely, and they don't you are going to find this problem in a couple possible places. It appears your battery is dead. Now, listen if your battery is not dead or is good, the cables (positive or negative could be loose, or bad connection. What could also of happened, to cause this is a couple of things. If you have a bad alternator as you were driving it, it would not be charging your battery and actually draining it, with all your electronics on while driving. So, when you parked it, that battery most likely is completely dead or a positive of ground from that battery if loose or poor connection, allow the alternator not to charge battery while driving.

In conclution. Check good the battery, and connections and then the alternator. Now, sense you have no testing equipment as you stated, hard to test the alternator, all you can do, is somehow charge your battery and get car going and try and drive to closest battery place, even auto zone can check your battery cells and your alternator. I hope this helps. Mike

I put a new battery in my chev equinox 2 weeks ago seemed ok if I drove it every day, but if I leave it a day its completely dead, alt is charging at 14.7 volts, the only thing on is the security light on...


You need to make sure that your getting good conection to your battery. If your alternator is fine, as you stated, you might not be getting a good conection. Your alternator may be keeping your battery alive just enough when your driving. Check all connections. Hope this helps.

2002 Ford F250 V10 new alternator good battery but it dies while you are driving


Does the battery charge even after it drains. Even though it's a new alternator, it could still be bad. The battery could even have a dead cell because it's draining while you're driving. Sounds mainly like the alternator output isn't enough. Internal voltage regulator inside the alternator is usually a big problem, it can't be replaced, except by a new alternator or have yous rebuilt.

2000 jetta has multiple alternator and battery failures


In my case, the instrument cluster was bad, causing the MFI display and radio to go haywire and putting a contstant drain on the battery. $760 to have the VW shop replace it. No problems related to the battery or alternator have occurred since.

Good luck.
