Battery Problem

[xt master]

I had a problem last winter that when I went to start the Jeep it was dead.I replaced the battery and still had problems off and on.I replaced the terminal ends on the wire and the problem seem to go away.Now it is cold out again and the problem returned.It was dark out and all I did was grab all the wires near the battery and shake and it started up.What suggestions do you have.It only seems to happen if the temp is below 10 degrees.No problems all summer long.:???:

Check the connections on the battery terminal and PDC.

I think so also.Seems if I wiggle the negative everything comes back to life.Now I just need to wait till the weekend to work on it.What a pain going to and coming home from work and it is dark out.Just boggles me that I only have the problem when it is cold out.

You certainly have a connection problem.

Do a voltage drop check under load to find it.
