Sorry Jeep Guy, First thing to do is check and see if you have a circuit which is draining....You can see if that's so by removing the positive or negative terminal and in a dark or shady place observe as you connect....If there is a circuit which is drawing power you'll see a small spark as you connect and disconnect....If you see a spark you'll know you have a circuit on....The heaver the spark the more power is being drained....Once you've confirmed that's what is happening you then go to the next step....Keep in mind that certain circuits remain live through out....The management system requires power for the internal memory....So does the music system and anything with a clock or savable memory....The power that is consumed by these is small and shouldn't run the battery flat, unless its in really bad condition.....If you crank the engine and it starts, how many times can you start, if you turn it on and off again and re start....Check that too because you could still be needing a new battery....After that if all is well with your electrical storage you'll need to check each circuit independently, until you find the one that's draining....Use a digital or analogue meter and go into the fuse box, remove one fuse at a time and check to see which circuit is live when it shouldn't be....Switch each circuit in turn and try find which is draining....You may have to remove bulbs and disconnect until you find out what it is that's draining....Is there anything which is malfunctioning in the vehicle? If so that's a good place to begin....It's a matter of trial and find....You don't want error....
If you think I can help more, don't hesitate....I'm here....Johngee10
Diconnect the neg, and bridge it with a test light, then pull fuses one at a time when the light goes off you have found the circuit, be warned the ecm fuse should pulled first as it has a constant draw
