I'm also having issue with power on and no PAS or throttle. Tried disconnect/ connect brake lines with no change. I then unplugged the throttle cable and when I plugged it back in the bike took off. Luckily it just hit my garage wall and I lifted up the back tire and powered it off. I (carefully) did the process again and the throttle stuck wide open again.  May just order a whole new wiring harness if available from Rad.
