Intermittent Or Random Loss Of Throttle Issue - E-Wheels EW-46 Service & Repair Manual

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.
