Fried ECM

That is what I did as well,(except the fusable link) with same results. Whoah
Except;
with the fusible link gone, you now have no protection in that hi-powered circuit. And so, if a short develops,your car could catch fire . What I did was run the ignition off a relay, triggered by the key, to remove the load from my OEM 1968 ignition switch. And then I subbed in a small gauge wire for the fusible link. Eventually, I found a correct F-Link and installed it. No more worries.

Thanks. I certainly do not want a fire. I'll try to source a new fusable link for protection. Will a fifty year old fusable link deteriorate over time?
