I have an circa-2012 R Martin ebike (36v14ah 500W TDCM motor, built in Texas) that I am trying to upgrade to a modern controller and computer. The battery finally went caput and I decided to upgrade while I'm at it. I'm trying to keep as much of the old hardware and wiring that I can as these bikes were built very well.
I'm trying to connect the PAS to the new KT controller - the controller uses three wires, the current PAS has FOUR wires. I can't find much material on how the R Martin bikes were wired and there is no identifying info on the PAS. I figure if I can find the + and - wires, I can put power on the device and rotate it to a magnet to find the wire that is supplying signal. That's my theory anyway.
Here's a photo of said connector, four wires red, yellow, orange, brown
Does anyone have any idea which wires it might be - maybe someone has experience with this manufacturer? Here is a link to the bike (I think it's interesting that the website still exists but no one is monitoring the email addresses on it): R Martin MiPower Electric Bike.
The new controller is a KT36/48v model (KT36/48ZWSRM-NBP03X) if it is of interest.
Thanks for the time and Cheers!
EDIT; I said 2017 but this bike was manufactured in 2012!
