Testing The Wire Harness - E-Wheels EW-46 Service & Repair Manual

Testing the Wire Harness:

To test that the wire harness is working properly, visually inspecting and running continuity
checks will be necessary. Touch your leads together to see if your specific multimeter beeps
when there is continuity.
If your leads are long enough, you can run test of both ends of each wire on the wire harness. If
your leads are not long enough to reach both ends of the harness, you can find something
conductive to cross the pins of two wires in a connector that are located right by each other
(screwdriver tip, paperclip, or any other conductive
item you have available to you). Doing this will allow
for one multimeter lead to receive the voltage being
sent from the other multimeter lead, which helps to
verify there are no breaks in the wires being tested. If
crossing connections, ensure that the power is turned
off, and that both ends of the wire harness are not
plugged in.
Focus on testing the throttle wires, rheostat (speed
knob/potentiometer), and brake sensors, which all
pertain to drivability issues. Testing accessory wiring
is not needed when diagnosing drivability issues.
If the wire harness has breaks that are not able to be repaired, please contact EWheels service
department directly for a replacement.
