Testing The Rheostat (Speed Knob/Potentiometer) - E-Wheels EW-46 Service & Repair Manual

Testing the Rheostat (Speed Knob/Potentiometer):

To test that the rheostat (speed knob/potentiometer) is working properly, you can disconnect it
from its wire harness connection, and try to see if a throttle response returns. This removes all
the limitation and ohm resistance from the positioning sensor in the throttle.
The rheostat can also be tested with a
multimeter. The rheostat will have an
OHM rating of 100k if it is a sport EW-
36, which is marked on the rheostat
itself. Set your multimeter to OHM
100K (or closest setting above 100K)
and use the two ports with the wires
soldered on to obtain an OHM reading.
Twist the knob with your leads attached,
and check that the rheostat varies from
approximately 0, to the 100k OHM's it is
rated for.
If the rheostat (speed
knob/potentiometer) is not working
properly, please contact EWheels
service department directly for a
replacement.
