My truck does not begin to turn over. It may be my battery but it was fine a day ago. When I got in the cab I heard a clicking sound inside the dash without the ignition on or anything. Any thoughts?

That is a common observation when the battery develops a shorted cell or is run down. To tell the condition of the battery, use an inexpensive digital voltmeter set to the 20-volt range to measure its voltage. If its good and fully-charged, it will read 12.6 volts. If it is good but fully-discharged, it will be close to 12.2 volts. If it has a shorted cell, it will be around 11 volts or less.
