Hello all,
I recently had a Montague e-bike come to me for repairs, in hacked up condition. According to the owner, it had stopped working. They ordered a new throttle hoping that would fix it.
The bike went to another person who hacked it up further. It came to me with wires cut and stripped.
The bike has a Crystalite controller 7840E and Phoenix II motor. The person I got it from tried various connections and was not able to get the motor to turn. The control panel does come on.
I have not been able to find any documentation on the controller.
It looks to me as if wires may have just broken loose from the board as flexible, silicone wires were not used.
I’m hoping somebody might recognize the device and know where the throttle connection is made. 3 wires come from the throttle, red, green and yellow, I would like to know their function. Also, is the throttle a potentiometer, signal generator, step controller or what?
The new throttle which was never connected came with no documentation either. I hope somebody can recognize and tell me the wire functions. It looks like something I see on eBay.
I did get hold of somebody at an email address on the controller, he said to replace with a controller, don’t remember which. About $500.
A search on eBay shows many controllers, from $35 and up. I would avoid the low end stuff. Any advice would be appreciated.
