Sw900 Error 10

[Paintpennn]

Recently changed the tire on my stealth bomber clone. It has a QS273 clone hub motor. It worked perfectly before I took the wheel off to change the tire. I reinstalled the wheel today and turned the ignition on and the display lights up but I twist the throttle and nothing happens. Like I said I'm running a QS273 clone motor with a sabaton 72150 controller, SW900 display and everything worked fine before I took it apart.. I labeled all the connections so I was sure to connect everything the same . It's got juice. I guess error 10 is communication error. Anybody know how I should go about solving this problem? I don't really know. .

A quick google says that error 10 for this display means it can't talk to the controller. Either the controller is not sending data to the LCD, or the LCD isn't sending to the controller.

This usually means that there's a wiring fault between the two, which could exist anywhere from the PCB inside their casings all the way to the connector pins between them.

Other possible problems: If the controller is not actually powering on, for instance, this will happen. You can check this at the throttle and hall sensor 5v lines--if there is 5v in both places, relative to battery negative, then the controller has been turned on.
If ther'es no 5v, the controller is not being turned on. Uusally when using a display, pressing the power button to turn the display on is what turns the controller on, by passing battery voltage from the B+ of the controller to the "lock" or keyswitch or ignition wire of the controller, using a tiny transistor in the display.

If the display's transistor fails (too high a voltage, too much current, etc), it won't turn the controller on by doing that job, and "nothing works" except the display turns on.

Having error code 10 on my sw900 hooked to a sabvotron 72150 controller running a qs273 hub motor . I started from a dead stop in the middle of a steep hill and shortly after I started up the Hill my bike started making a funny grinding noise and then I saw a little puff of smoking. Shortly after that I got an area code 10. Pas went to zero and no throttle response. Don't know where to start

Where did the smoke come from? That's where your failure is, and is where you would start.

If there was smoke, there is probably still a smell on the blown or burned parts even if there's nothing visible.


It could also be related to your previous error code 10 problem (in this thread) that you never resolved. (or if you did, you never posted your problem and fix here).


It could also be related to your overheating issues here:

Sabvoton 72150 is hot

Hi, I'm new to ebikes. I recently bought a stealth bomber clone off alibaba. 12,000(allegedly) watt 2.5T motor with Sabvoton 150amp controller pretty standard fare . It has 72v 40 ah battery. Seems to run fine. Its a blast to ride. The other day after riding I took the battery cover off and the...

Oh with the previous error 10 problem I had mismatched one of the connectors. It was a silly mistake that I made. This is more serious I'm afraid. The smoke came from the controller or spaghetti jumble of wires crammed into the bomber battery compartment/frame. The conttroller has a flashing green light that should just be a steady green light. I'm pretty sure I fried something in the controller.

Thinking about getting a fardriver controller as a replacement. When selecting a controller I want to match the 72v and the max..? amps that the battery puts out ? Model number of current controller is 72150 means 72volts and 150 amps right?
