HEI Module/E-coil...compatible with factory fusable link?

For those of you who have done the HEI module or stealth HEI, have you had problems using the factory fusable link that feeds the coil? I'm using the Ford e-coil and running into problems. I think I've narrowed it down to this.

Have you guys bypassed the link?

The 14 ga fuse link wire on that circuit hooks up at the fender solenoid. It blows 'just' before something catches fire (hopefully) so that means you have a dead short in your wiring someplace.

If you bypass the fuse link, make sure you have a couple fire extinguishers handy and the fire department on the speed dial...

I have seen folks use an inline fuse and even a headlight for a temporary connection while they tried to track down the short circuit.

Odd. If you really ran it this way you probably cannot shut your engine off. or something else wierd will happen I think. Are you perhaps using a relay inline with the feed from the fuseable link to power the ignition coil?

There is a resistor wire feeding the coil, and it's not a problem.

The fusible links protect the main alternator wire,
And the main fuse block wire,

The ignition circuit is protected by a 3 to 5 Amp FUSE in the fuse block, not a fusible link.
