Alternator Problems Then Motor Problems

If your flywheel, while bolted to the crank flange, can be shifted in a fore/aft direction for more than 12 thousands of an inch, then the thrust bearing on the crankshaft (integral with one of the main bearings, IIRC) is worn out.

My guess would require LOTS of movement fore and aft, close to 1/4inch. Also, you would find large debris in the oil pan. If neither of these are true, your engine may be just fine.

But when I got my motor out and before I took off the flywheel, i could move around quite a bit, I'd say around 1/4 inch or so. But when I was moving it around it got kinda stuck/jammed and didn't really move that much anymore.
I went to the Home Depot after that to get a 1/2 in 14mm for my impact gun and took the flywheel off

By the way, here in the UK, a back and forth movement in a shaft is called 'end float', is is called the same in the USA? 1/4 inch end float is huge and I would definitely have a look inside to see what's wrong. The centre main crank bearing has two thrust surfaces. Bearings are easy to fit but the real cost is in any work that might be required to the crank journals. I recently paid about over £100 to have my crank done (a first class job but London is one of the most expensive cities in the world) but I think it's worth it.

Today I stuck a flat head in one of the holes for the flywheel and moved my crank around and heard it go " clunk clunk clunk " on the inside of the motor so I'd say those thrust bearings are shot .
