Hi

I've just received a couple of MAC motors and 12 FET controllers but i'm slightly confused around the wiring.
- Some are obviously obvious but not all, and the examples i've found on this site and google images don't perfectly align.

Any assistance would be appreciated :D

From where?

but i'm slightly confused around the wiring.
What info does the seller have on their website ad for this specific controller?


We can guess, based on other stuff posted around here on ES, but there's no certainty to any of it unless the seller provided a diagram. So on with the guesses:

1 battery.
2 self learn.
3 throttle or pas
4 halls
5 throttle or pas
6 ebrake
7 display or programming
8 throttle or pas
9 display or programming or CA-DP
10 phases,

They're all just guesses, though. If you open hte controller up, you can trace each wire to pads on the ocntroller PCB to see if any of them have labelling that matches functions on similar controlllers, but even if they do it's still only a guess that they have the same functions. :(
 
I got them from directly from MAC Motor - I'll contact them and see what I can find out.

Thanks for your help.
 
My guesses:
1 - Battery
2 - Regen enable
3 - 3 speed switch
4 - Programming
5 - PAS
6 - E-brake
7 - Throttle, Power ON/OFF combo
8 - Halls
9 - CA-DP
10 - Motor phase

edit: switched two.
logic:
battery and phase are easy. connector 8 is a common hall connector for cheap chinese stuff; bad lighting, but i'd guess 5 pins wired up, since i didn't see temp sensing on the controller features. the description mentions regen enabled by jumper, so that explains 2. the CA cable is a guess, but easy to check, since the wire color order matches the CA male end. PAS is usually a 3 wire connector, so 5. that leaves programming, on/off, and throttle for the 2 remaining 5 pin connectors.

to test, connect the battery. get a voltmeter and check for battery level voltage on the JSTs. that will be the one that has the on/off feature. the CA will have battery level, but only after the controller is turned on. once you turn on the controller, you can check which of the other connectors has 5V, and which 5 pin is for the CA.
 
I ain't gonna guess. What you need is a trial and error procedure, and the people who really know this stuff may be able to help with that.

Obviously, you need the power, and everyone agrees that's those Powerpole connectors. You might be able to diagnose many things without the motor hooked up? But might as well, since it appears to be clear enough they're the other fat wires.

So, what's next? What if you plug #4 into a halls socket, and it's really programming? Maybe better to try #8 first? Etc.

The local expert who put together my setup, wired up the plugs so it was more or less impossible to go wrong. Combination of mostly black, some white plugs, male/female directions, such that if it was a black male with 3 prongs, there was only one place it could go, etc. I doubt MAC was quite that diligent, but you might have a look if you haven't already.
