Electrical mystery 94 Cherokee - Please HELP
I have a 94 Jeep Cherokee. Car won't start due to no power to the car. Battery was replaced 6-7 months ago. Car acts totally dead and opened up hood to take a look. First thing I did was touch the battery cables to see if they are loose or damaged. The terminal was tight on the battery and the cables seem tight in the terminal, but when I touched the cable it instantly clicked and power juiced through the car and Immediately lights came on and inside door buzzer came on. It sustains power for approx 15 seconds and then dies back off. The buzzer fades off over a span of a few seconds its not an immediate cut off, seems like power drains out instead of cuts off. I then touched the positive cable and it clicked and repeated the same process. I tried messing with the cables again and it did not repeat anymore. Next I went to the fuse box in the engine compartment. I pulled the starter fuse and it looked good. As soon as i put the starter fuse back in the battery did its click and the car had power for approx 20 seconds and then out again. If i repeated that step it would do the same thing, but not with any of the other fuses. I cannot get the car to keep power for more than 20 seconds. And I tried putting the fuse in and as soon as i hear the click i run to the ignition and try to start it and I get nothing.
So does anybody have any clue what may be causing this issue? or at least have some good brainstorming tips of things to try to check out or look into? thank you for all help.
