ever since i had the new motor pu in my car will drain a battery in about 1 day. i have now bought a deep cycle battery just so i can keep jumping it to get it started. i can charge it all night long and drive it for a few hours come back out 5 hours later and its dead. i had it set up on a trickle charger and it will not keep it charged, so i figure its using all the juice the charger is giving it. any ideas? i checked all the lights under the hood, trunk and in the car. im lost.
