Hi there, I went on a 5 mile ride today and just as I was at my location I lost all power to the motor, throttle and PAS, but there was still power getting to the display, ( kt35a controller 900s display)
I wasn't pushing it too hard for most of the journey and was mostly using the assist on level 4. I checked the controller and it was extremely hot, so I opened it up but there were no obvious signs of any problems or any burnt smells. So I gave it 20 minutes to cool down and powered it back on, but still nothing.
So I disconnected and reconnected everything and powered it on, and there was a very small puff of smoke from the controller where from I couldn't tell, but there was still power getting to the display so I tried the PAS and nothing but trying the throttle there was a kind of faint clunk sound as if the motor was trying to move, so I powered of then again but no clunk sound this time, but still display power.
Any ideas on what it could be? My first thought would be the 5v blown in the controller but when I've experienced it before the display wouldn't power on. I wasn't able to test as I took my voltmeter but forgot the leads. I've had to leave it where it is as had to get home fast for an emergency.
I've ordered a new controller a kt 45A 18 fett so a small upgrade from the included one, but I'm concerned that it might be motor related. If it is the motor would it cause any damage to the new controller when I connect it?
Thank you
