Trust the voice of experience here, anything is possible when it comes to a 30+ year old Bronco. I believe yours is a '77, correct? It's the curse of Early Bronco ownership that things seem to slip, loosen, or break for no apparent reason. It sounds as if you have been turning the engine over repeatedly attempting to start it while searching for the source of your charging problem. It is probable that the engine could have jumped timing or that something has broken internally (timing chain or gears, distributor gear). To rule out whether it has jumped timing or not, mark the location of your distributor with a Sharpie or some other marker. Loosen the hold down clamp and rotate your distributor slightly in one direction or the other while someone turns the ignition key for you. If it has indeed jumped timing, the engine may attempt to start as you move the distributor. If it doesn't start, then you can always put your distributor back to its original position....
