Nothing After Ignition

Trouble turning on:

1.Make sure you turn the key and that it is charged. There is a breaker in front of the battery, breaker needs turned on before operating.







Make sure to also check if the screw terminals are tight, if it's loose the power wire could not be making contact!













2. There is a fuse in a small white box, check that the fuse is intact. If not swap it out. There is an extra fuse in the box. Its a 5amp 250 watt fast acting glass fuse (6mmx30mm) if you need another. Without that fuse the controller is not turned ON and the lights and dashboard are not getting any power.


















3. Ignition

The ignition contacts could be corroded it's pretty common if water got in.

Remove the 2 bolts holding the USB/ignition assembly and pull from the top, you should have a simple connector with 2 wires, unplug it and measure the continuity between the 2 pins when the switch it ON, if you don't hear a beep them it's possible the switch is finished. You can bypass the switch with a piece of wire to see if the bike will power up.
























4. Measure the voltage of the battery. T

Measure the voltage with a multimeter: flip the ignition OFF ,then the breaker OFF, unplug the battery fully, wait 30sec, and measure from the charge port, you should be reading anything between 45V up to 67.2V depending on the state of charge.


















Next would be to plug the battery back, measure the voltage from the charge port (see attached) and while measuring flip the breaker ON (note the voltage) then turn the ignition "ON" and measure the voltage again. As you can see in my case the voltage went up a little .. that is because the BMS was sleeping and we just woke him up (really). If you turn off the breaker and wait 30 sec or so the voltage should go back down a little (in this case it dropped 0.4V)

















5. IF you had a weird battery reading, like voltage dropping under 45V when you switched the ignition, Unplug both front and rear lights, if one of them is shorted out the main display and the motor wont run. You can access the headlight connector under the ignition and access the rear light connectors from the back of the rear light.

6.. Battery load testing:

Best is to use a 120VAC incandescent bulb or a halogen bulb as they work great with any voltage, at 60VDC they will be roughly 30-40% of the regular brightness. If you have a large resistors be aware that you will need to apply a small load like a light bulb before apply a large load of the BMs will trip instantly.

Unplug the battery from the bike, let it rest for at least 30 secs, measure the voltage from the battery pack. Then connect the light bulb to the discharge port (there is no polarity on a incandescent light bulb). If you see the voltage drop (like these 2 pictures below) then it's likely the battery BMS that has an issue. In this situation please contact

If not please continue testing
