This usually happens if the connections are dirty, corroded, or a connector is loose. Make sure to check thoroughly, and repair as necessary.

If they're dirty, spray contact cleaner or brake cleaner into the connections, and clean it out with a small screw driver or nail. Once you think it's clean, spray out the connection once again and let it dry. After it drys, put some dielectric grease on the contacts, and put it back together.
