1968 El Co Ignition/Power Issue

Hi Guys, i'm new to this group of El Co's. I just picked up a '68 SS Clone, 396 4 spd car.

Car was not running when I went to see it. Previous owner thinks there is an ignition switch problem. So I got the car to turn over with a remote starter.

With my test light there is a real weak light at the fuse box. When I turn the key to start it, there is no power at the fuse box. When I turn on the Hazard flasher switch, there is no power at the fuse box either. This leads me to believe this is not specifically an ignition switch issue.

Now, there is only 1 ground strap that I can see from the body to the block and I don't see one from the frame to the body.

Can this be causing the loss of voltage to the fuse box? Or is it that there may be a short somewhere? I'll start with the ground strap but any other suggestions would be great! thanks in advance.

Check your inline fusible links. One is next to horn relay and another is next to battery.

But you'll appreciate me soon. You're gonna be hangin' on for mercy when I get this sucker rollin'.

One question, if the fusible links were bad or blown, I wouldn't have power to the fuse box correct?

Sounds like bad connections at the bulkhead connector.

At the fusebox? Or the bulkhead from the fusebox? or am I way off?

Check both sides. I rewired my 68 and none of the engine lights and other front electric worked. It was a loose bulkhead in engine bay which I believe is connected by two bolts.

Check the fuse box also which is connected by two screws. Good luck.

I had a wiring harness that had a fusible link hanging on by a strand or two next to the horn relay. Electrical problems suck..I know I've been working on mine for days.

Electrical problems are easier solved with a wiring diagram. At least you can trace the particular circuit, and using a voltmeter, find the problem. Maybe you can find one online, I don't know. Sounds like your dealing with a poor connection, broken wire, something of that nature.

Thank you Rookie chevelle, good possibility, it definitely seems a novice wirer has been under the hood and under the dash.

Just strange to me that not only does power stop when turning the key, it also stops when i put hazard switch on.
