Made up a new motor control system with two SSR relays. One is an AC ssr that is used as a latching relay, and one DC ssr to switch the motor ecu on and off.

A big part of this project, is to use recycled materials as much as possible, hence the wooden platform in the photo below. The wood was discarded stock picked up for free and coated in acrylic varnish. The two bus bars are the 12v bus bars that all other 12v electrics on the bike will derive from (lights, horn, indicators etc).
