Unwanted motor operation

Saturday discovery... Upon wiring a logic power switch into the controller power wires I had uncontrolled throttle ... Apparently the GND on pin 13 that I had been using for the throttle ground is not the same as pin 5 GND and after switching things seem a lot more stable and smooth on the throttle. I also added a chrome plated 15 pin connector cover to it to protect the pins. Looking forward to testing at 33 volts (8 cells) next.

Seems to run ok now and the on/off (grounding) switch really helps initialize the logic. Had my rpm limit set to 2000 so I raised that so it may go faster now ... Next chance I get I will try that. I get a bit of surging at full acceleration like some limit is cutting in and out.
