The red lock wire needs to connect to B+ to power up the controller.

Well my last issue was the sense wires rubbing on the cover inside the motor. Went to smaller wires so clearances solved. Tried to get it running, no go. Brushless Tester before install had phase and halls working good.

Single Red wire is the lock or ignition wire, I just hardwire it to the red battery wire.

I've got a cheap as chips mhf 300 p shunt meter that can control a relay with undervolt or overcurrent etc so I use that to switch the red wire to battery's positive that way I protect battery from going to low on any cell count then I stop the factory low voltage being a problem by setting it to minimum and use the shunt dispatched as my dash all I need to keep the ride safe.

Thanks guys! up and running on the bench setup with the 1000w model now! It was spinning backwards but I plugged in the self learn while it was on again and it its spinning in the correct direction now. Super. Just need to figure out the other bits of wiring as to what I want from it and go from there. 8)

How does one use PAS with these? I think I will need to add a connection for a CA then run everything though that and use the CA to deal with the PAS settings.. thoughts?

So from the CA manual I need:

1 - VBatt = 48v+ which is easy.
2 - GND = GND which is also easy.
3 - BI = Shunt (-) ==> Can I use the shunt within the controller?.. - yes.
4 - W = Shunt (+) ==> same question as above - yes.
5 - Y - Speed ==> not sure where to take this from. Dur, hall sensor.
6 - G - ThrOut ==> Dur, throttle signal. Sorted.

*[EDIT] all explained pretty simply here: http://www.ebikeschool.com/add-cycle-an ... ontroller/

Now with CA as well. Win. Suspect something is wrong with using the controller shunt - the current figure on the CA is considerably lower than that coming out (allegedly) from the bench top test power supply. hmmm. Pretty exciting now that its all working! 8)

You probably just need to set the CA to the actual value of hte shunt. I know it's in one of these, but I dont' recall which one

Yes, I thought the known resistance could be off/incorrect. I will look into that tomorrow. I think accessing/programming will be the next step with this. 8)

If you solder off the LVC solder jumper, does it revert back to a 48V 13S controller of something like like 42V LVC (as stated on hksunwins 48V models.)

I am totally guessing that it just might. I was using 60V battery back with the LVC unsoldered on a hksunwin 60V controller, working fine. I just kept a very close eye on the voltage. Now I am using 10S 36V pack and I get nothing. Funny thing is though that the Self Study works, throttle does not reverse the rotation, so I tested it and the throttle, its fine. I can touch the red and sensor wires on the controller and it will reverse. Ignition is connected up.

I see no 48V LVC pads on the pcb. Been looking carefully around the area where the LVC pads are, and over the entire board and I see nothing. hksunwin sells no 36V model, so that brings me back to if no LVC pads are jumpered, its goes to a 48V controller with a LVC of 42, so 13S is 54.6V, and a 42V LVC is 3.25V/cell.

Before I do anything, I will see what I can do to add to my 10S 36V battery, might just have to go back to 60V.

I confirmed that soldering off all LVC jumpers on the pcb, gives you a 48V controller with a LVC of 42V I used a measured ~80V battery 20S battery in which it worked, obviously! and I hooked up a 10S which I measured at ~41.25V which is fully charged. I'm not about to up it to 42.5V or 43V to test it. Looking back my previous pack on that controller was 15S, ~60V and it worked good. I currently have 2 hksunwin controllers with their LVC pads soldered off, and waiting on a 48V 1000W model to be delivered, which will have 60V caps most likely.

I had a 80V 470uF cap break off at its leads, it was on the end of the board, on the other side of where the wires come in, and other side of fets, right in the corner.

The symptom was it was hard to get going, but once going it was fine.
