Alibaba's efoil - help with throubleshooting

Hi,

I have an efoil from Alibaba, honestly it used to work perfectly, used to. Now motor cannot be run, but remote controller is connected and I can modify the speed but with no result on motor. I suspect connection between motor and inverter (btw this device between battery and motor is called inverter?), so I replaced plugs, however issue still exist. Any idea how to continue troubleshooting?

I wanted to upload video, but forum does not allow too.

Does anyone know/ have some user manual for thie efoil where some typical errors will be described?

Welcome to the forum.

Pretty hard to help you with the minimal information you supplied. There are a lot of different companies that make efoils and each approach is a bit different.

Please supply additional info such as brand, are there any labels on the components. How old is it, is battery charged etc etc.

I orderd efoil from Underice company from Alibaba one year ago.
Today I realized red light on the controller blinks always, nevermind if there is connected motor or not. That is why I suspect the problem is with controller or with receiver for remote controller. Anyway try to troubleshoot it somehow.

I will let you know how supplier is willing to help after one year warranty

Hisun efoil? Esc looks to be the same as in this one

Also this one:

Several have asked questions here about broken ones, none have succeeded to fix them - as far as i know.

This doesn’t mean it’s hard though, only that it takes a bit of effort.

First use a voltmeter with cable tester. Test if All connections and wires are having contact. If not you got a cable or connector Problem. If cable is good open what you call inverter and share pictures then we can help. Your esc, remote, motor or battery could have a Problem, hard to say. Find out where the receiver of the remote is. Maybe inside what you call inverter.
