Today I fitted a Pertronix Ignitor ignition module in our Patrol to replace the points, and also one of their "Flame Thrower" coils.

As soon as I tried to start it I noticed it was cranking slower than usual. Thought it may have been trying to kick back, so retarded the spark a bit.
When I was retarding the spark I noticed something smelt a bit hot, but couldn't see anything, so figured it must just be the new coil warming up.
Tried to start it again, got it to fire once then it died. Look under the bonnet and there's smoke coming out from under the air cleaner. Freaked a bit till it cleared, then could see that it had blown a fusible link.
Now it wont crank over (obviously no power to the starter).

Could a faulty coil draw enough current to blow the link? Or even just the high performance factor cause too much draw?
Read on another forum that there have been a few epoxy "Flame Throwers" which were faulty from the factory.

Any other ideas as to what might've gone wrong?
Thanks.
