Trouble-shoot directions for ignition/no start

My issue was the connector on the wiring harness side of the fusible link had a broken off locking tab.  The connectors stayed together only via friction and had become disconnected.  Couldn't see the disconnect at first as DPO had put a wrap of duct tape around it, in lieu of replacing the broken connector.  

The consequences of having that fusible link fail while on a road trip are so high that I bought a new spare fusible link.  Also bought a new wiring harness side blade and plastic shell.  Didn't need to replace the blade, which is 8+mm in width, but I did have to destroy the old plastic connector shell to install the new shell.

I got these from Banzai Motor Works www.zzxdatsun.com  $15 for the WH03 fusible link and $7.50 for the WH03/05 connector.

Hope this helps.
