You have to jump start your car everyday installed a new battery and alternator what could be the problem?

There could be something draining your battery. With everything switched off, use an ammeter in line with your main battery terminal. Anything more than 250mA drain means there is a problem. Some vehicles have a small current usage, for an alarm system, computer or radio memory.
Favourite culprit is an interior or trunk light.
If you find a current drain, remove each fuse in turn to find the likely circuit involved.

You should have a heavy red wire going to the back of the alternator, it should have 12 volts, it will excite the alternator, thus allowing it to charge your battery. If the doesn't have 12 volt, trace the wire, I believe that it will end at the starter.

If you have 12 volts at this wire, most likely you have a fusable link that's shorted out at the starter. Look for a wire at the starter that appears burnt, or wiggle the wires one at a time, you'll find on that feels like a plain rubberband, with no resistance while wiggling.
