clean all your cables..charge the battery..then check the voltage at the battery..next start the jeep and check the voltage with it running..let us know what readings you get

The battery is brand new replaced it today. My jeep wont start to get a reading. The voltage meter on the dash reads 8. I cleaned the posts and made sure all of them were connected properly. The starter wont even crank over anymore. It ran fine before a big freeze hit.

meters on the dash might not read accurate..check battery with a volt meter..if the battery is new and charged then it should read at the least 12 volts

The battery reads 14. When the cables are connected an i try to start it the starter wont turn over and the whole system goes dead like i tripped something. I go back and readjust te cables and the dash works again. Could the cables itself be bad?

sounds like they are either bad or not getting a good connection..did you clean the glaze off the new battery posts?? sometimes that can keep you from getting a solid connection

Yea I did. Im going to see if the battery cables are bad and replace the connectors. Im also going to strip the starter and see if thats the issue as well. Either way it has something to do with it. Idk if it could be the coil either. This jeep has seen better days.

coil shouldn't have anything to do with the starter operating

True just trying to eliminate the possibilities. Its kinda hit and miss at the moment.

Measure the voltage down at the starer too.

Cables do go bad. Post #5 points in that direction.
