What is your question?
2003 Jeep grand Cherokee unlimited v8 4.7 remote key won't open door so I used key it opened. Jeep wouldn't start so I hooked up gully charged Mini Max Cat jumper and without it even turned on my lights inside and dashboard lights lit up but keep turning on and off and when I turn on Mini Max to jump it by the time I get to turn the key it turns off. Tried jumping it with a diesel truck that has 2 batteries and it tries to start a little then nothing. Before all this my daughter had my jeep and it had a loose connection to the battery but instead of calling me she had some guy screw with it and what I was told is he took the battery out of my jeep charged it some and put it back it and it started so she drove it home. It sat a couple days before I tried starting it but she failed to tell me any of this until a couple days into can't figure out why it won't start. Now I just found out the guy bought a part for $64 & put in my jeep but don't know what the part is and the guy is in jail.
