New controller with display for Fano-Tex FT-7009E with Bafang 36V front wheel motor?

[Tobias Claren]

Hello.

I own a Fano-Tec FT-7009E.
It has a Bafang 36V front wheel motor.
Controller G3M20211-1592-16 and the simple LED880 display.

Now, after cleaning, the motor no longer works.
There was a little water in the controller plugs.
Even after blowing it out and heating it up for a long time with a hair dryer, nothing has changed.

Now would be a good opportunity not only to buy an identical replacement (€6), but to see if there is something better available.
Of course, this should still be worthwhile for a cheap tricycle from China.

What would you recommend here?


Thank you.

Can you show the controller label and a picture of ALL the wires and connectors spread out so that we can see what it is.

Water shouldn't damage anything unless you got in in the 5-way connector that goes to the 880 panel. Before anything, check that the motor connector is in ALL THE WAY TO THE MARKED LINE, not just in tight. 1mm short can cause non-function.

Here is the controller:


The Cables:



The thick white 5-pin plug is very firmly seated with hot glue.
It no longer worked after cleaning.
The cables were not moved at any time.
After drying, I pressed all the plugs firmly into each other.

Are they tide marks on the controller. Looking at those and the corrosion on the screws and plates, it looks like the bottom corner of the controller has been under water a lot and at least one time half of the whole box has been submerged. Is that right?

I can tell you now that you'll be very lucky to get a plug in replacement for that controller, even though I still can't see all the wires. You might as well get one with an LCD.
