You cleaned the cable, but what about the other cable?
Does it have the water it needs in the cells?
I think it went dead for one of two reasons, it self discharged.
O it was discharged by a component in the vehicle.
The starter relay on the fender gets its power from the clutch switch or the jumper in its place.
That power comes from neutral/start circuit. The ignition switch sends it to neutral/start.
Those are not fruit flies ! you have a dead banana
Ignition switch has nothing to do with the headlights. The lights will work so long as the battery, cables and light switch are good. Sounds to me like a dead battery or corroded connection somewhere along the line.
your headlights should work without the ignition switch ! check for corrode on the battery cables and the battery posts ! also it could be the starter ! the starter is where the hot cable runs to and if it,s shorting out you won,t have anything !
Its a 1979 Ford F250 460. Heres the scenario 2 days ago i parked it running great, now today I go to turn it over and nothing no headlights, hazards horn radio nothing. I cleaned the terminal just in case and a jumpstart from my brother but theres still no power, I've already changed the solenoid a week ago. Could an ignition switch just go out like that. I dont know do you have any ideas.......keep in mined its a 79 not a 2014 lol.
