Quick Hall Effect Throttle
No test equipment necessary
Your electric scooter controller will not accept throttle commands
This is an easy test to perform.
Hall Effect throttles have three wires, Red, Black and usually one of
the following a green, yellow or blue.
Controller outputs on Red 3.4-5VDC
Check Your POT Throttle here
1. Remove fuse
2. Elevate rear wheel ( we will
try to make it spin at full speed )
3. Turn key to off position
4. Make a circuit between the three
accelerator / deraillur wires from controller
( This is where the three throttle
wires mentioned above plug into the controller )
5. Replace fuse
Be sure scooter is stable
Stay clear of rear wheel
6. Turn key to on position
7. Turn key to off position
End of test
If the motor did not spin you have
another problem. ( bad connection, batteries, controller, key switch
If the motor spins there is a short in the throttle system.
Check all connections and look for broken wires.
24V controllers will not have full
function when system voltage falls below 21 volts or each of two
batteries falls below 10.5V.
36V controllers will not have full function when system voltage falls
below 31.5 volts or each of three batteries falls below 10.5V.
SMART charging systems work the same way.
24V chargers will refuse when system voltage falls below 20.5
36V chargers will refuse when system voltage falls below 31.5 (
Ex. 44VDC output SMART charger refuse a 24v system)
