I have 05 f150 4x4 auto 5.4the other day I turn the key to start it. It cranked over like normal then it stopped turning over, all my lights and gauges went crazy blinking on and off even the fuel pump was going on and off know when I try to crank it over it acts like the battery is dead the starter just cliks I put my charger on it still nothing. It has 50k miles still the original battery any Ideas thanks ED

 

put a new battery in it. It seems to have solved the problem
