magic external controller options

[A Brinkman]

anyone familiar with the magic external controller enough to tell me how to wire the soft shut off. There is a jumper between the 5v terminal s and I suspect I can simply cut the switch in series with these terminals, but would like to confirm. The manual claims there is a theft protection option available if this soft is used, any truth to that ? and any opinions on the use of this option ?

thanks in advance for all of your wisdom and insight

Unfortunately, neither the eBike D.I.Y User Manual nor the Prokit 901/902 technical Manual has been updated in the last 11 years, but during this time many changes have been made to both the controllers and the wiring. 

To my knowledge, the Anti-Theft alarm function has not been available on the external controller for at least 9 years and I'm pretty sure that the "soft-switch" (or "Lock" switch shown in the following diagram) was only used for controllers that supported the Anti-Theft function:



Early controllers had an external wire looped between the "B+" connector and the "G" terminal that could be cut to to allow the switch to be inserted if required:



But some controllers appear to have the battery feed directly connected to the "G" terminal inside the controller:

I've had the same problem with one of my magic controllers (36v V2)..
The 'G' wire had no effect on "turning off" the controller.
I suspect, by mistake (or on purpose), they soldered the 'g' wire connection to the main power line INSIDE the controller.
I wanted to use it for setting the alarm function, but alas, couldn't.

I'm not quite sure what you mean by "There is a jumper between the 5v terminal s and I suspect I can simply cut the switch in series with these terminals" so it's difficult to comment on this.



Which terminals on the above controller are you referring to?
