1972 429 no start no crank issue

[72' Betty]

Hey, ive been battling with what seems to be an electrical issue for awhile now and im stumped. When I try to start the car all I get is a click from a relay thats right next to the brake servo, some kinda blower/horn relay. The interior and exterior lights do not dim when trying to start and i hear no movement from the starter. I shorted the solenoid which is attached to my starter (not on the inner fender like most cars) but got nothing but sparks, starter still wasent moving.

This is just extra info about the car that im unsure if its relevant to my issue. I used to have to push the top of the steering wheel in to get it to start (ignition switch issue maybe?). I also hear a faint buzzing from inside the dash I dont know if its always been doing that or not. The battery sits at 12.24v but I even tried jumping it with a battery charger and it still wouldn't start. Many have told me to replace the neutral safety switch or the ignition switch but I dont want to tear out half of my steering column if thats not the actual issue. Any ideas would be greatly appreciated, im trying to fix it up for use in my engagement and wedding in the near future.

First thing to do is make sure you have a good, fully charged battery and battery cables are good with clean connections.

Battery voltage of 12.24 volts, measured at the terminals, indicates the battery is 50% discharged. If you can't charge it up to where the resting voltage is around 12.8 volts, then the battery is likely defective.

Battery cables deteriorate over time. They may look good from the outside but no longer able to conduct the full power needed to kick over the starter. Make sure cable connection points are clean and bright.

Ill have to go out and buy a new battery and try that out. The one I have now doesn't hold a charge, within about 5 minutes it loses its charge and goes back to 12.24v. I did replace the battery terminals and snipped off some of the old copper wire so I could get a clean connection on the terminals. Ill update if the battery wasent the only issue

If your battery is bad I think you would still get something from the starter even a slow crank. I thik you've gotta pull the starte and jump it out on the floor. Starters are very torquey so be careful.If the stater checks out on the floor then I would start at the cable to the starter and go one step at a time back to the battery. Godd Luck and keep us updated.
