Lessons Learned....Heed my advice...
For starters, With a Classic Ford, You NEED to start with these 3 basics, or your car will put you in the looney bin trying to diagnose it.
1. Make sure that you have a good Interstate or Exide made Battery or (Optima Red or Yellow if you want to spend the cash)....and quality Battery cables with clean connections.
2. Make sure that you have one of these for your Voltage Regulator......A High Quality Motorcraft or Standard Motor Parts Solid State Voltage Regulator. This will keep your car and your Alternator charging at its most op[timal level...all the time and is die-hard reliable....No archaic points used. Leave points for the distributor!
Buy one of these below...
3. Make sure that you have a Quality Starter solenoid. IMHO, This is one of the biggest woes of new Classic Ford owners... Using a Brand-X or other brand Solenoid (They are all trash) other than a Motorcraft, Standard Motor Parts or Original OEM Autolite starter solenoid will leave you stranded on the road somewhere or in your own driveway in no time flat. DO NOT use Repro Solenoids either (Also Trash). Classic cases of one of these starter solenoids going bad is the car still runs with the ignition key removed, or just does not start at all, or even worse, The starter stays engaged while the car is still running! I've seen that one too. So get a good one....Buy the one below..
Once you've done all three things above, You are NOW ready to diagnose your car. You say that you have a grinding noise. That could be the Flywheel and Torque Converter scraping up against each other.....or your starter solenoid is so cheaply made that its "crapping out" on you causing one of the conditions that I mentioned above.
The exact car that you own is a pleasure to drive and die-hard reliable if you do the right things and use the correct parts. I can vouch for that as I have two of them....A 1965 Convertible I6 and a 1966 Convertible I6.
Also, Do yourself a favor and pick up one of these too while you are at it.... It's always good to know that your car is charging...and/or Battery is good.
