Looking for an electronics hobbyist/technician in Colchester to help with an EV diagnostic puzzle!I have a 2019 Govecs Pro Cargo electric scooter. The 72V traction battery is fully healthy and charges fine, but the bike won't drive due to an ECU communication error / CAN-bus fault preventing the throttle signal from processing. Standard bike garages won't touch it because it's purely a digital/electronics issue. Happy to pay for someone's time if they have experience tracing wiring faults, testing controllers, or diagnosing EV communication lines!.

I have a bike where the motor is getting main power, but the ECU isn't sending the 'go' signal. The previous mechanic found a heavily corroded connector down by the footboard but couldn't fix the communication fault. I need an electrical specialist to trace the signal or check the ECU

Anyone that can help? stopped working and i noticed a loose cable but i cant find where to connect it, neither the garages but they dont do electri bikes, im sure is something easy for a savvy person.


I have a 2019 Govecs Pro Cargo electric delivery scooter that has become a non-runner. Standard petrol bike garages won't touch it, so I'm looking for some advice from the EV electronics experts here.The Symptoms:- The main traction battery is fully healthy and charges completely fine. - The bike turns on, but it will not throttle or engage the drive.- The diagnostic points to an ECU communication error / CAN-bus line fault between the controller and the throttle/display.Has anyone dealt with the CAN-bus wiring or controller pinouts on the 2019 Pro Cargo models? Any advice on where to start probing with a multimeter to trace this communication blackout would be highly appreciated! Based in Colchester, UK. Thanks in advance!
 
Dismantle the front, until you can see all the cables and their Plugs. unplug and replug them a few times, make sure they're properly fastened afterwards.
Additionally unplug the 35 pole Amopol plug from the controller under the seat and plug it back in properly.
Where is that "loose cable" coming from?
Pictures?

Hi! I did almost all what you asked except the 35 pole amopol plug from controller under the seat I removed the ECU for ultrasound cleaning in case it has water or corrosion then loose cable is next to stand sensor that was disconnected too . I bypass it but when I do bike thinks stand is on all the time so I left them alone and isolated them. Are you local to Colchester?
