It would seem that the primary is shorted. If you have a ohmmeter check
the resistance between the plug prongs. If you get ~0 ohms that means
there is a dead short. If it is a short-circuit. You'd have to find
where it is. I presume that is the cause of the tar leaking. A short was
created and it melted the tar and the wires together. If you can trace
it to where it is shorting (if it is) then just snip off before the
short and add a new cable. 
If you do not get a short reading (not 0 ohms) then I'm stumped too :)

hope this helps.
