My truck has sat all Summer, just got around to putting a new radiator in it as well as alternator.
I have charged the battery and cleaned the terminals (ground is clean on both ends).
I have no headlights and it iwll not turn over. Yet I do have 4 way flashers and it will turn over if you cross the starter terminals. No spark at the coil though. This is with the switch turned on.
Could it be a bad ignition switch?

Posibly it could be but sounds like yourmissing a wire to the bat. or a broken wire. I would check the power units like where fuses and relay are located to see if it is getting power.
