My 1972 Mustang Coupe likes to blow fuses. I bought a new lighter and element installed them, after cleaning all the rust and filth, when I push the lighter in the fuse blows. I've run continuity between the power and ground, ground is good and the power only grounds when the lighter is pushed in. I've tried it with the lighter installed in the dash and with it dangling, making sure I'm not grounding out anywhere. The horn is on the same fuse, but I've got it disassembled at the horn button, and it works with everything hooked up. By the service manual these are the only things on that fuse. I'm assuming (I know) that the way it's supposed to work is push in lighter, you get resistance, element heats up, gets to certain temp., lighter pops out. Is this incorrect? Or am I missing something obvious?

Just replaced the one in my 65... all cruded up, and if you push in the lighter it won't stay, but if you hold it in it heats up fine. It only has one wire going to it for hot lead, and the housing is the ground to the dash. Put in the new housing and it works correctly with either lighter. Of course, I only need mine for a power source since i gave up smoking the day i had heart surgery. Still not sure if that's because I saw the error of my ways or because I didn't live. : 0 )
How many amps is the fuse rated at?
When you say "lighter and element", does that include the socket? If not, maybe that element is wrong for your socket.

You say you cleared the rust and filth.... go back and recheck the ground! Make very sure you have a clean metal to metal contact. Also make sure there are no open breaks in the wiring which could short out the circuit.
It's either God telling you to quit smoking or the spirit of Shinoda telling you to *QUIT* smoking in a classic Mustang.
I think you need to return the new lighter and socket for another one. From what you've said, it sounds like it is shorting directly instead of going through the coil.
