    Severe Motor Chattering Problem?

    I haven’t tried that. I can swap the CAV3 easily, so maybe I’ll give that a shot first. Might rule out a CA issue?

    Severe Motor Chattering Problem?

    I also get a throttle input signal on the CA3 indicating correct voltage between 1v - 4v, so I’m leaning towards a bad controller.

    Severe Motor Chattering Problem?

    I went ahead and performed a Hall Sensor & Motor Coil Test and it checked good. Video Below. Then I went ahead and performed a motor controller output test. This did not look normal. Possible issue. With the throttle applied steady… out stops. Here’s a video I did a couple years ago on how...

    Severe Motor Chattering Problem?

    I have a few bikes I built that I use for e-bike tours. When I built them in 2019, they worked great. But lately, one by one they have begun to severely chatter under load. The stuttering start has really been hard on clutches, even shearing an axle key. 100-200 miles if that. I have changed...

    GPS chip locator provides some reassurance, but I don't leave it unattended often. A key disables electrics, but doesn't stop anyone from pedaling away. The built-in cubby can carry a locking device. It does gather a crowd though... maybe that will help. Valets keep an eye on it too.

    New Kit Installed... But no worky?

    I agree. EM3ev is replacing it. I'll install the new one step at a time monitoring the 5vdc circuit with my VOM.

    New Kit Installed... But no worky?

    Thanks for your responses. Once I finally got some diagrams with pin out voltages, I quickly discovered the motor controller +5vdc reference voltage for the throttle sensor and hall sensors was only putting out +.5vdc. That's not going to work very well. I'm not certain how the 5vdc low voltage...

    New Kit Installed... But no worky?

    I just fitted my bike with an EM3ev Kit with the Mac 500/1000W Rear Gear Hub (12T), 12 fet 40a Motor Controller, and a 50v (Samsung 25R) 12.3ah Li Ion BMS. I also purchased a Cycle Analyst V2.3 with Speedo Cable. It worked briefly for 100 yards or so, but now, I get nothing. The BMS has 58.0V...
