I think I may see a problem, the yellow wire that powers the ignition switch has a fusible link right where it connects to battery side of starter relay. It looks blown, could this possibly be a factor?

It certainly won't help things. You can do a continuity check on it to verify if it is bad. If you have nice pointy probes on your meter, or just trace it out to a start and end point. That could be why the PO had the push start and stuff on it. But try to find it on your diagram and see what circuit it is supposed to protect. Might be for something else?

This would be so much easier in person. I know it must be frustrating for you to try to follow all my crazy instructions.

I can't make out on the diagram you posted what that wire is going to, more because of my bad eyes than anything else. Have no clue what or where my diagram got to. I've pretty much rewired my own way the car I have, so the diagram at this point is useless for my car.

But remember, if it is blown it did it for a reason. So don't replace it with regular wire, and try to figure out why it blew first. Probably one of the hacks the PO did caused it though.

I'll definitely check this out asap tomorrow, and yeah the s lug wire is 16ga with voltage both with wire and without. Both times key in at start or out of switch didn't matter. Thanks for the info on the manual too. Hope things look better for you soon. I'll be posting soon of my findings.

It's very possible, he had that thing redneck special. Which as soon as this thing gets running will be more undoing of his rigging on various other areas of the car lol.

I just checked, there is an adjustment that can be made on the actuator rod that goes from the key switch to the ignition switch. That could be needed to be done. I tried to print and the scan the instructions, but I have no clue where this thing put the scans.

Ok bought a new fusible link for the relay. Old one was definitely fried, haven't installed it yet. Bought a new key cylinder instead of adjusting old one. And looking at fuse block I found severe corrosion etc. So I'm replacing it with an updated blade fuse block. Will post more as it comes along.
