Don't you just hate it when

I finally got her somewhat in tune, so I took her out for a test drive. The wife got in and we took it around the block a couple times until she stopped dead. Nothing. Except the speedometer says we are traveling at 45 mph.
I thought it was the fusible link I put in earlier. I popped the hood and see the fuse is good, but there is a bunch of smoke. I see that the fairly long positive battery cable has fallen over against the exhaust manifold. So I grab the wire to pull it off and slightly burnt some fingers.
We walk home, get my car and go back to Natalie and jump start her. No Problem. Back into the garage.
Hopefully tomorrow she gets new brakes
