Hi all
What could be some causes of a motor turning by itself? Im not getting any error or throttle error. The twist throttle worked fine but ill try another to see if thats is the problem.
When i power the QS motor to the sabvoton..nothing moves but after 5 to 10 seconds..the motor will turn and sometimes at dangerously high speeds.
Ill have to look at the wiring but it seems ok atm.
Have any of you experienced this?
Thanks!
 
I got stuck about 4 miles from home two days ago.

It was the throttle line. Going high. When I tuned the bars. Sat there fiddling for a hour.

Got home and replaced the connector and its been fine since. Twoish years old on that connector, replaced with high quality.

What else could it be?

If the problem goes away when you unplug the throttle, then the problem is the throttle.
 
Check for throttle ground wire almost cut, or ground circuit almost interrupted at connector contact. A poor neutral continuity does make voltage surges on a circuit.
