Hello everybody☺️ I am glad to be here and looking forward to a good discussion.
First of all, I am new here. Therefore I will shortly introduce myself.
I am Nico and currently I study Physics.
In my freetime I like to build and repair stuff. Especially big battery's.
A few years ago I got myself an electric unicycle, monowheel or however you call that.
The battery bms was broken so I replaced and resolder that. Nothing big.
I used this thing for some years and had a lot of fun. Unfortunately I used it last time in heavy rain. Usually everything should be sealed but accidentally some water came inside. But I think at that time it was already to late. It was turning on but it blinked weird and I could realise some electronic smell from inside. I immediately opened everything and cleaned it. I realised, that there was no real water inside the electronics compartment only some moisture and corroison from the long use. I cleaned everything up but still nothing. I found out that the region in the picture (Coil and Diode) got really hot and emit that smell. Also there was a short circuit in the capacitor region. I measured the Diode and found out that there is a connection from both sides. The multimeter beeped. I am not an expert in electronics so I unsoldered the Diode. The Short circuit disappeared at the capacitors but still it seems like I have not solved the problem.
What do you guys think?
What could be the problem?
And will a Diode replacement solve it?
Thanks in advance for any help☺️
