stalls when hed lights turned on
My truck starts and runs fine. Right turn, hazards, and dash lights don't work. When I turn on the head lights she dies. Won't start with head lights on. But with the switch pushed in(off) starts right up? This just happened tonight. Took it out 2 nights ago and everything worked fine. Any help and I would be great full. 96 F150 XL 4.9 4X4

Wow, sounds like you have some significant electrical issues. Blowing any fuses?
Everything worked fine until the other night?
I've seen partially un-plugged connectors cause lots of strange symptoms. I'd check the firewall bulkhead connector, and the ignition switch connector. Also, the headlight switch connector often gets hot & partially melts...
After that, get a good wiring diagram, meter, & test light, and start tracing out circuits...
