blowing fuses

just had a question, last night I blew the fuse in my headlight switch, lost head lights and dash lights. replaced it today and then blew my main light fuse, if I put the fuse in when the switch is pulled out all the way it does not blow but the second I hit the middle notch in the switch I blow the fuse again. What the heck is happening? any ideas? thanks

also will not blow when pushed in all the way but when pulled out and hits mid it blows the fuse again.

Russell,

I don't have the same switch but if it's a typical light switch.
Full in is off?
Mid is running lights/dash lights
Full out is to power hdlights
Fuses blow due to excessive amps. If you are blowing fuses when only the running lights on but ok with all on---that's a strange one. Maybe the switch itself shorts to grnd as you
move it? Isolate the wires from the switch, use a fused jumper wire from power to the isolated circuit-see if it blows?
Good luck.

Do you have VS rear Teardrop tail lights this sounds very familiar.

yeah I have the tear drop tail lights. And yes full in is all off first click is running lights and dash lights full out is all on. I am going to try jumping the wires and see what happens I will keep posting on results in case someone else has a similar problem.

not jump, isolate the wires from the switch then supply them with the alternate power source.

Check the two parking light connections in the head lights, the ground and battery terminal are close together and can cause a blown fuse in the first pull out position.
