Sometimes the car starts sometimes it doesn't...when it doesn't, if you wiggle the battery cables it will start. we checked the battery, it's good, only a year old. Also, when you're driving, sometimes the radio and all electrical will go out inside...the car is still running but everything else shuts off and then comes back on.

If it will start after you 'wiggle' the battery cables, you don't have a tight connection. Remove the cables, clean all the connections with a wire brush, then make sure you firmly attach cables. Connections MUST be clean and tight. If you continue to have trouble, check the connections at the other end of the cables (starter and ground), as the 'wiggle fix' may be a loose or dirty connection at the other end of the cables. This is probably also the cause of your elec. problems, hopefully once connections are cleaned and tightened properly, all will be fixed.
