Machine locked up.
I was sewing binding on my quilt and it stopped. The needle won't budge (of course it froze needle down), the hand wheel won't turn. I managed to get the needle out of the binding so I could remove it. I took the housing off, couldn't see any obvious problem. It's a Brother 1500 PS so it's all mechanical, easy to see most problems. Nothing in the bobbin area looked out of place. So I have it in the shop now. It needed the reverse lever spring re strung anyway(it popped off a few months ago) This machine is years old, first model of the 1500. I love it. I will post what the problem was as soon as it's fixed. I know many here have this machine and will want to know what it was in case their machine has the same problem.
