1973 International Scout Starter

Electrical problem
1973 International Scout V8 Four Wheel Drive Manual Unknow miles

Have a quick question (at least I think it's quick).

I have a '73 International Scout II. It has a dead spot on the flywheel, so every now and again (approx. Every 6-7 starts) there's a good singing going on. Typically, I'll re-try and it'll start.

On Saturday I had a beast of a time trying to start it. It eventually worked, but took awhile. I didn't do any driving Sunday, but tried to fire her up tonight. The first time, it hit that dead spot and sang. The second time it tried to start but wouldn't turn over (which isn't altogether atypical. It takes awhile to start when it's cold anyway).

However, I tried a 3rd time and nothing. I turned the key in the ignition to the spot where it would usually the engine would kick in and start trying to turn over, but now nothing. No sounds, no turning over, nothing. I think it's done this before, but usually I'll reset the key and turn the ignition again and it'll trigger the engine. This time however I tried five or six time and nothing. It was as if the ignition wasn't triggering the starter or something. Not sure.

Is this indicative of a starter issue, or a wiring issue in the steering column? Or, is it something altogether different.

Any help would be greatly appreciated!

Best,

Tom
