Well she decided to stall on me today. It would stop and go kind of on it's own. Wiggling the connector on the driver board appears to get response. If I had to bet, it's the 3 wire connector (yellow/blue/green) and labeled on board connector as (In/Gnd/+5V). Would this explain the symptoms?
With it stalled and everything connected, I was able to measure 5 VDC across the blue and green crimps by pinning right from the top of the connector. However, I am not sure it was getting carried over to the board. Then with everything still connected, I used a pic and pushed the green wire's crimp towards the board from behind and that may have done it. Is there any technique for "tightening" up those female crimps inside that connnector for a better fit?
