Testing controller, motor, display

[Polaris steve]

I am trying to test to see if motor and controller work. I don’t know how.
I bought a tester but not having much luck.
is there a way to power up th motor by bypassing the controller? I have wheel off bike,
I also don’t get power to the display. How can I check that?
i remover the controller also.
any help will be much appreciated. Thanks

No, you cannot bypass a three phase motor. It needs to be driven by a controller.

This tester is mainly useful for checking the Hall sensors on the motor, using the rectangular 2x3 connector. Hooked up, the LED's flash when you rotate the wheel. You have to spin backwards if it's a geared motor. Spin it slow to make sure you see all three sensors toggle.

It would be nice if we could hook a controller output to the tester and see the lights on the right go round and round, but it doesn't do that.

Are you working with the controller/display originally intended for the motor?

Basic motor test is to disconnect the three heavy phase wires. See if it spins freely. Then touch blue to yellow. blue to green, green to yellow, that simulates regenerative braking and the motor should turn harder. If it is a geared motor, you spin backwards because it free wheels if spun forward.IF no change with a phase wire shorted, the motor has an open coil and is bad, Next, you connect the motor wires and it should spin freely. If it does not, then the controller has a short circuit.

First order of business, if the controller and display are a match is to get the display lit up. Every LCD display I know only needs power/ground to power up. After that, if there is a communications problem they will often show an error signal. If it is a simple LED display only need power/ground to turn on. Power being the battery voltage. So if you can find a wiring diagram for tour display, locate power/ground and see if you have 36V, 48V or whatever you battery supplies.;

All of this assumes everything was matched. If your subbing in different controller or another display, then you have the possible wiring changes to worry about. And displays only work with the ocntrllwers they were designed to work with, They're not interchangeable,

Thanks Harrys,
I was hoping the tester could test controller, now I know it can’t.
I have 2 Polaris 2013 vector bikes, one works the other doesn’t. It is a Proprietary system, it is 30 volts
I don’t know if the display works. I don’t want to use the 30volt battery to test the display if not going through controller. Do you think I can use a flashlight 1.5 or 9 volt battery to just check display?
is there a way to check each component,PAS, brake sensor, etc individually?
an direction will help.
Worst case, I will buy a conversion kit for rear wheel and battery to match.
Any thoughts on conversion kits?
Thanks again for our input.

That's a Bionx system, isn't it?

Thanks,
I don’t know if it is Bionx. .
The display motor controller, PAS, Brakes, everything is original from Polaris when built.
I will try again what you said in your reply, I’ll get back to you as I move along.
Hope you are safe from Corona virus, have a great weekend.
