New Brake Lever... Now Not Working

[Biggles]

Hi

I have changed the brake lever on my ebike (Windgoo B3) and now I can't get the motor to spin up. I have checked the connection and operation of the new lever switch and its working fine and in the same way as the original lever.

Everything else has remained the same. I cut the original wire and connected the brake lever into the original wire.

Any suggestions at what could be the problem.

G'day Biggles.
Test the switch. Most test " off " ( open ) with the lever released. A very few test " on " when released. Check the old one to make sure it's normally off then that the new is the same. It could also be that the switch on the new lever isn't adjusted right & is always on. Make sure it switches on when you pull the lever & off when you release it. If it doesn't, either the new switch is bad, not screwed in fully or the lever has a stop screw that's screwed in too far, not letting the lever to fully return.

Isolate the issue first to make sure it's the brake lever by unplugging it. If the bike spins up, you know it's the lever/switch.

Hi All

OK i have taken everything back to original. Sadly it still doesn't spin up.

Where can I learn more about how controllers work and how to test outputs etc?

I am wondering if the throttle might be at fault as it was a bit sticky not releasing sometimes. I had to remove it to put on the new brake lever that side. Is there a way to bypass the throttle input to start the motor?

Is there a Windgoo b3 expert forum anywhere? It also is know under a few different names but is the same thing.

To be clear, you've disconnected both brake lever connectors and the motor won't spin, correct?

Overwhelming odds are that you have a bad plug connection or a damaged wire somewhere.

Yes exactly back to original. I retraced my steps.

I have disconnected and reconnected all the plugs in wiring also still not working.

Is there anyway to check the power at the heavy motor wires?

Leave the levers disconnected for the remainder of your troubleshooting until you get the motor to respond. Do you have a multimeter?
