Yes, not needing to be manually coaxed because I tested it ahead with a battery across the motor wires, but with one off to isolate the sense chip.
I don’t know if that is totally necessary, I only used a 1.5v battery that is kind of weak now.

It looks like, the testing with a volt meter there are issues of low voltage and a missing ground. Tony can respond. I followed his guidance!
