Hi,

I am having an issue with my baserunner controller from grin. I have assembled my bike, and had the baserunner working briefly for programming. Then after I went to use it and take it for a test run it would not turn on. The battery is fully changed and outputting 58v (measured). I began going through the controller debugging steps, so testing resistance to the phase wires and continuity between other connections.

Here are my findings:

No resistance from +ve to -ve power teminals
Yes resistance between throttle gnd and +ve power terminal

Resistance between +ve and 3 phase outputs
Resistance between yellow and blue phase, and throttle gnd.
No resistance between green phase and throttle gnd.


No resistance between -ve power terminal and 3 phase outputs
No continuity between throttle gnd and -ve power terminal
Yes continuity between throttle gnd and higo ground.

I think my issue is with -ve power terminal... does anyone have any input or thoughts?
 
Did you check all the connection to make sure the connectors are fully seated etc...?
 
Throttle only. I have shorted the hidden wires yellow and white. I also have the following adapter which shorts the required wires in the CA plug.
