Hey guys I have a 2003 Mustang. Lately I've been having issues with the battery; or so I thought. On random occasions my car wouldn't start, I would attempt to jump it off but no luck. But when I moved the wires it cranked. Now it's happening again, of course I wiggled the wires but it didn't work this time. I tested the battery with my voltmeter and it is charged. When I opened my door I heard a clicking noise coming from under the dash. When I got down there to check it seems the clicking is coming from or near the fuse box. Could this be an ignition relay or switch? Or bad wiring. Also I have no aftermarket electrical items except radio. Thanks

From what you've described, it would appear your issue is more than likely from a bad wire or switch/relay as mentioned. At any rate, I'd start there by having your electrical system checked In the meantime, welcome to TMS.
