I have an ebike that I am putting together. It uses an instant start Crystalyte 72V 40A Speed Controller and a Phoenix Brute (5305) motor.
I got the motor and the controller from two different sources. The motor had trailer connector and the controller had Anderson connectors for the power wires. I matched colors and switched the motor to Andersons.
I'm finding that the motor doesn't want to start without some help and it shudders and jerks at low speeds and under load. After it gets up to speed it smooths out and seems to run with good power.
Before I got my battery, I hooked up the controller to a small AC adapter for a computer to see if things would light up. I moved the throttle accidentally and the motor tried to start. I did the same again and the motor wouldn't do this again. I don't know how underpowering might damage something, but, maybe I did some damage?
Looking at the color combinations at the hall connectors I get:
Motor Controller
Brown Red
Black Black
Green Brown
Yellow Yellow
Blue Blue
I left the
Motor Controller
Brown Red
Black Black
alone and tried all combinations of the other wires and the motor wouldn't start with the wheel off the ground. I found in a post somewhere that sometimes Crystalite controllers use a brown wire for the green wire. I also tried putting contact cleaner on the connections and trying all the combinations and that didn't work either.
I found a couple links on the subject of diagnosing controller/motor issues:

I measured some voltages and resistance on the hall bundle, but, am not sure how to interpret the results:
Power Unplugged, Hall Bundle Unplugged
Red - Black 4.3V
Power Unplugged, Hall Bundle Plugged
Red - Black 4.3V
Yellow - Black 18mV - 5V
Blue - Black 19mV - 4.5V
Green - Black 19mV - 5V
Resistance
Power Unplugged, Hall Bundle Unplugged
Yellow - Black infinite
Blue - Black infinite
Green - Black infinite
Brown - Black infinite
I think the fact that all of the hall sensors have essentially the same reading is a good sign for the motor. I'm not sure about the resistance values though.
I read in one of the other posts that the voltage between red and black on the controller side should be 12-14V and with it plugged in it should be 6-9V.
Can anyone help?
