Sorry didn’t quite explain that right. The dialectic grease went between the rubber gasket and the engine casing particularly round the sockets.
The grease I packed inside the casing behind the chainring was Lucas Red n Tacky marine stuff. Cheers
My Mythique is now up and running again! Woo Hoo!
New connector board seems to have fixed it. At least a quick trip up and down the street shows its ok so far 🤞
There was signs of water ingress/corrosion on the soldered pins on the back of the connector blocks and one or two of the tracks looked...
The most important place would between the right hand crank bearing and where it goes inside of the side cover. Mine had none, just aluminium corrosion.
I would apply grease sparingly on the moving parts as the controller is a bit exposed. Also there is large hole through to the actual motor...
That bearing in mine had water in it as well. Slight corrosion but I cleaned it and repacked it also. Needs changed. I’ve been checking out seal orientation and it seems that in this type of application it allows the grease to purge outwards.
Well that didn’t go well. Split the motor carefully. A few drops of water fell out! Got the 2 halfs apart - water everywhere, on the controller, on the gears, even in the electric motor itself. I can see how to gets in from the trail of corrosion on the aluminium cover. As skismith said earlier...
When mine started to go wonky, a combination of button pushes randomly got it working till it went completely dead. The error codes I got varied but mostly 36 and 5.
New display, button remote and wiring loom made no difference to mine. New display I got was Ver3. Original was Ver2.
My bike ran...
The battery sounds good then.
Mine was the same, power at the yellow plug. Looking at the power boards for sale I see there is a circuit board on the back and a series of tracks close together to a white connector block. Could be a place for moisture to cause havoc if not sealed properly?
I’m also in the same boat. Changed everything bar the motor and the battery. My battery is operating the same as yours. I’m assuming it’s ok but not 100% sure.
I’ll go down the motor controller route when I’m convinced the battery is ok.
Not sure how to do that though?
I’m a bit concerned that...
Thanks for help guys. I was going to try and recover money from PayPal but I think I’ll try a repair as it’s such a good bike. How easy is it to get the correct controller and K1flash? Cheers
Also noticed that the yellow main power socket on the motor has a hole in the middle and on mine you can see the green back of the controller connecting board. There’s a black seal between the board and the side of the motor but this connector goes through it.
Maybe water can get in this way?
That was last week, said because of circumstances they couldn’t take bike back for repair. Suggested I contact Bafang. Now there’s no reply at all so far for information about the motor. Not their fault of course. Awful business.
Another dead Mythique here.
Wet ride, started to malfunction, wouldn’t switch off, code 36 on screen, pulled battery, put it back and it turned on, still code 36. Dried display and buttons, dried connections at motor - worked fine. Went back an hour later - completely dead!
New display and...
