Having an odd issue with my 1995 F150 XLT. Tried to start it the other day. Opened the door, normal lights, sounds, etc. Turned the ignition and nothing. Fiddling to turn everything off thinking it was a battery charge problem I stumbled on the odd occurrence that it would start if I pulled the headlight switch into a certain position. Had this happen a number of times since, and today I tried to start it and found that the battery is completely dead. I'm assuming there's a short somewhere that's draining the battery, but I'm curious how the headlight switch could affect or impact starting the vehicle. Just trying to see if anyone know of any oddities or peculiarities related to this model that might be related to this.

Thanks.

 

If I understand you correctly, you get nothing when you go to start it , but if you fiddle with the headlite sw it will start. If that is so,,,,,,,,,,,,,,,

there is nothing wrong with the battery.
There is , however, a poor connection in the circuit to energize the starter. Evidently , when you increase the load on the system it allows a path for the starter to operate.

The system , without looking at a diagram, starts at the power to the fuse panel and any fuses that go to the ignition syst.
Since we can't see everything , I would suggest starting at the battery and cleaning all the cable connections. Both positive and ground cables. That go to the fuse panel and just remove some fuses one at a time and reinstall them and see if there is any improvement.Sometime a poor connection at a fuse location can produce problems like this.
If there is no noticeable difference , there could be a connection problem in the rest of the circuit that energizes the starter relay.
Don't forget to confirm good ground connections for the starter relay that is either mounted on the inner fender well or the firewall.
