A friend wants to run a CA on a Mac controller that doesn’t have a direct plugin option. The main lead from the controller runs the Mac display and takes the throttle signal so I’m fairly sure all the signals are available for a CA.
The black and red wires give battery voltage as per CA wiring.
I need to find out the colours for shunt pos and neg, and throttle signal. The speed signal is not required as we are using a magnetic wheel sender.
Does anyone know the wiring in these Mac controllers or know how to test for the right signals. See photos below.
The round Mac connector that plugs into the Mac display has its wires circled in red at the board end.
Thank you for any help.
