Intermittent or Random Loss of Throttle Issue
The scooter could be intermittently driving, or not consistently accelerating for three different reasons.
It could be a loose connection, a tension issue in the brake handle, or an issue with the batteries under
load.
1. Loose Connection
For random loss of throttle response while driving, start by checking both ends of the wire harness
connections for a loose wire pin or connector. Focus on wiring pertaining to drivability (throttle, brake
sensors, motor wires, speed knob wires).
2. Brake Tension
Lack of tension in the brake handle is the most likely
culprit to cause random loss of throttle response while
driving. The brake cables can slightly stretch out during
normal usage, and the brake pads will wear from
normal usage. When the cable stretches and the brake
pads wear, this can cause the brake handle to become
loose and have a slight amount of play, which can cause
the brake sensor to activate while riding randomly. To
test if there is a lack of tension in the brake handle, use
one finger, and tap the brake handle towards the hand
grip with the scooter power turned on. If the brake
lights turn on and off while you tap the handle with a
single finger, then this is the issue.
