Need help with CA throttle override

[Mondo]

Hi all - I'm trying to setup the throttle override wth the Cyclone motor controller.

I'm trying to determine where the resistor that is in series with the throttle might sit. I've taken a photo of the relevant connector inside the controller. I can see one SMT resistor and one normal one. I'm wondering if someone a bit more savvy with controller circuit design can help with identifying the correct place for tapping into the board.



The trouble is opening up the throttle body itself to trace it back looks tricky to say the least..

thanks

Mondo

Hi Mondo-
This is something I've been meaning to tackle myself but other issues have forced their way to the front of the queue. I found this picture over at ypedal's site (I hope he doesn't mind me borrowing it)



So the yellow wire or pin 5 is the one the resistor goes on. If you can trace that back to the controller you should be rockin. If you can't find it on the controller PCB itself, you could just heat shrink one on the throttle wire somewhere, maybe at the connector.

Does anyone one what one of these 7 pin connectors is called and where I can order one from?

Not sure of the official name, but I've always seen them referred to as "Crystalyte connectors". I got a bag of them from ebikes.ca (search for "conbag"), but they only include 3-6 pin connectors in the bag. Since only 6 pins appear to be used on the throttle connector you could replace it with one of the 6-pin connectors instead.
