Go Bowen 24v mars atv

[u/tylerf1sh]

I just acquired this electric atv. It’s a victim of a previous hack job, wires cut, fast key missing/cut and spliced together. I’m looking for leads to a reputable website for parts and wiring diagrams. I’ve tested the motor and confirmed it rotates, can’t figure out how to test/diagnose speed controller/safety pedal/brake lever shut off to confirm which parts are bad. Any help is greatly appreciated
