..update.. so i loosely connected a battery to controller and throttle to controller on the kitchen table.. to see if i could further diagnose anything... good/bad news... it appears theres a short in the throttle wiring about a foot down... as i held the throttle the lights were flickering on and off.. if i squeeze and bend the line it makes it go on and off... so that seems to be that issue... for now...

next would be solving the blue phase wire issue
