Well the truck battery keeps dying, i alredy put a new battery and changed the alternator twice. I took it to the parts store to get it checked out and its reading low charge. I dnt know what to do any more, i think i have a short some were but dnt know were. Can i get some help any ideas? The only light that comes on in the dash is the battery i checked all the fooses and nothing. A good charged battery would last about a week before it died, but now it kills it like in 20 mins.:smt100

Trace the wires from the alternator to the battery. I haven't had this problem with a ford before, but in a previous life: Ive had some wires/fusable links melt between the aternator and battery. Change the fusable links while you are there. Clean battery terminals???

Have you used a multimeter on the battery as the truck is running? See how many volts are going to the battery from the alternator (13-15). If not, then you have a charging problem. If so, then you have an open circut somewhere draining your battery.

Sounds like you have a draw on the system. A short would do nothing but pop a fuse or burn the harness up. I'd look up how to perform a draw test and start there.

start buy pulling the fuses one by one and narrow the draw down then check the things that are run by that fuse..that is the easyest way...
