older Roo/Shamrock hybrids never had a factory cutoff switch.
only since the past couple of years.
did you remove and replace the battery?
if so, you may have reversed the wires which will trip a resettable breaker that's tucked in along the A-frame.
it's gray or silver and has a tiny black button on it. just press it to reset the breaker.
