Thanks a lot, @Alan all this help is highly appreciated, I usually repair graphic cards in spare time, but this board got me talking to my gpt more than to myself. I had to reverse engineer the whole thing until I found out I was wrongly thinking signal wire is the GND wire. Was a very hard learning.

After all, the second board is fully functional now.

Thanks again, if you know where I can get this SMP5-20150702.OC8 firmware it would be helpful, otherwise not sure if its dump-able, but should be I think .

Hi andto the forum.

ebikes.ca produce a torque arm that is designed to use existing eyelet mounts on either the rear frame or the front fork.

Check out the TorqArm V5 on their website or watch the YouTube video here.

You can even download a full scale drawing to enable you to print and cut out the pieces to test the fit on your bike before purchasing.

I think the V6 or V7 TorqArms would be a much better choice as they transfer the torsional force much further away from the dropouts, which should greatly reduce any chance of the dropout breaking due to metal fatigue from the bidirectional axle torque being constantly applied directly to it during both power and regen, which the dropouts were never designed to withstand.

It’s a battery level meter and quite accurate. The. Buttons are on/off and speed mode, which doesn’t seem to make any difference. You can also use the buttons to reprogram the throttle so it works the opposite way round.

Thanks again once more Alan, much appreciate all the questions and the questions.

Regarding that diode in the photo is indeed burned, and its on the other board not the new one, the new board is fine.

Are you using a 36V battery for testing? If not, why did you change the voltage setting to 36V?

Alan

I actually plan to keep the 36v battery for it, not only for testing, or should be 48v?

I think I have the TRC010, although not 100% sure. The connection was straight forward though, just plugging in the connectors.

I also experienced shuddering at higher revs. That was due to an firmware update changing the scale of controller setting but without the actual settings being changed accordingly. That was solved by an email to GM though.

Here's my blog post about installing the throttle.
