Hello again,my Truck is not starting when I turn the key I hear a solid and single click and the panels light turn off,if I turn the key back the panels ligh are on again so it is bad battery or bad starter Ps.same thing happened couple days ago and I just move the positive cable and the Truck start but no luck today

 

It's either a bad cable connection or a dying battery.

 

Thanks GLC It was a loose cable
