Inmotion V5F died after riding the curb

[Tomasz Czyż]

Hello

I have a damaged v5f. After driving onto the curb it suddenly turned off. The Cap5 capacitor and the U13 audio amplifier were damaged. The capacitor was replaced, U13 desoldered because it had a short circuit on the power supply. V5F is still dead. Resistance on the Cap5 pins 30Ω. Please help or schematic board.

It may be easiest to buy a new controller board.  Once you have components going short circuit then it's possible (probable?) that they will have damaged other components too.

KS & IM is the easiest to repair, GW & VS will burnt much more components & also the pcb tracks as well bcos they don't use any fuse. i've repaired an IM for a rider friend recently, U13 probably is not the cause of short but the mosfets are. i just replace the fuse & a single mosfet & its up & running, Good Luck.

Spoiler

Check all the mosfets for short circuit, it could just be a single mosfet or a pair.

I am afraid that everything on the power line where the capacitor is damaged is broken. 
My guess is that the voltage stabilizer has been damaged. Maybe I will have more time on the weekend, I will check something. A board diagram would be helpful.
