My battery keeeps getting drained

Run your vehicle turn on radio headlights wipers heat disconnect the positive side of you battery if the vehicle dies its still your altanator but also check the cable from your altanator to make sure it's not broke anywhere.

It sounds to me like you have something binding up or building resistance due to heat. I have had a similar thing happen to me with different cars. It turned out to be a battery cable that was fine when cold, but when it warmed up, it would sag and touch against an exhaust pipe just enough so that when I went to start the vehicle, it would arc to the exhaust and lose battery power that was normally used for starting it. Another time it turned out to be the negative cable not making good enough contact. The Ford 300, 6cyl. engine is a very good solid dependable unit, but ford has always had quite long battery cables and issues with the way the were grounded. I would check my cables and maybe replace them for good measure. Also be certain that your negative cable is very solidly grounded to the block of the engine.

altanator or battey .. startup and pull neg cable . if it stops its your alt.

A new alternator doesnt mean it good,The alternator needs to be recheck,Just make sure all your connection are good

One quick way to check the alt. is when it is running discounect the pos. cable and if the engine dies it is a bad alt. If it stays running it's good. Let me know if this was helpful.

A fresh charged battery does not mean it is a good battery.The battery is working the alternator to death,replace it,it has a bad cell,or the amps are to low,and has a short in it.The alternator senses the battery is in bad need off charge,and puts all out until the alternator has nothing left,This is the most likely cause of this problem.Also be sure the battery cable ends are shiny clean when replacing the battery.

get a schematic for the car.if the alternator went,it could have taken out the 18 gauge fuse link in the feedback circuit that switches on the alternator

check the battery connection first sounds like bad connection, test battery if good check battery cables for worn insulation

Did you ever figure this problem out? I am having the same issue! i bought a new battery, new alternator, but my jeep keeps dying! i did the battery draw test, as soon as i pulled the fuse block battery feed out the draw was completely gone. can you please tell me what you did, this has been driving me crazy for over a month!

are all wires, and battery cables clean and tight, if so check for a bad ground in charging curcuit.
