When i turn the key to start my jeep the battery kicks on and the dash lights up but when i try to start it completly it dies, it makes a click noise then theres no battery power. I leave the key on, get out and wiggle the black battery wire until the battery registers again and then i try to start it. Usally takes a few times to get it to start its a pain in the ass. Any ideas what it could be. i dont think its the battery cause it starts after a few times.
